    • User Sanctioning: Warn or ban users sharing unwanted code patterns.

Changelog:

Update v5.1

  • With %disableAllMessages% you can now optionally disable all messages that appears after a action is done.
    • For now, it’s not possible to disable single arguments, cause this would break the script
  • Fixed some typos

  • Added inbuild detection for Vip and Subscribers to be optionally exempt from moderation.
  • Vip and Subscribers can be exempt from moderation individually. If a user has both roles, either one of the exemptions will match on 'True'.
  • Twitch bot account is now exempt by default, regardless of it’s role.
  • Globally, URL detection does now look for indicators in messages, rather then banning straight forward for just finding a blacklisted word.

v3.8
I decided to make 2 versions of the script. A Light version that only blocks/bans urls/obfuscated urls and the stable version.

Stable Version

  • Reworked the Code for better detection and differentiation between the systems
  • Revised the appearance of the script structure and made it more understandable
  • All chat messages and Logs have been revised and unified to be more informative
  • Removed the filter for specialCharacters since it was pretty unpredictable.
  • Voucher Code detection is fully integrated.

Light Version

  • Added a “light version” that only delete/bans normal urls or obfuscated urls while ignoring urls concealed with “***” or anything else.
  • Offers the same customization options as the stable version.
  • This Version is “as is”, since it’s pretty forward and as long twitch or SB don’t do groundbreaking changes to APIs, there is nothing to do here.

v3.7

  • Again refined the detection for special characters to avoid issues.
  • Added more editable messages according to new features.
  • Added Killswitches for new features to bypass them if there are any issues
  • The special characters and voucher code pattern detection, both now can differentiate between spam messages and normal messages and only ban typical spam messages
  • At the moment, you need to go into the code to edit the exclude lists for special characters if you’re using a language using other chars then predefined

    grafik
  • Added previous versions in the Changelog area so older versions are available if needed
  • Message args in the Permit User action are also now mandatory to be active and set
    TwitchLinkGuard-3.7.sb (24.9 KB)

v3.6

  • Refined the detection for special characters to leave out some common characters to avoid issues in some languages.
  • All Chat Messages are now directly handled by the corresponding arguments that were disabled by default and optional till now.
  • All Mod-Action log messages are now editable.
  • In the TLG-Options the args %whitelist%, %suspiciousKeywords% and %suspiciousEndings% needs to be active.
  • isVip is reintroduced as if/else statement since not everyone trusts their own VIPs.
  • TLG now detects messages containing “voucher code” like structures like: GVP-1KJN-VM12-2QNG and ban users without roles/trusted group/not permitted.
  • Performance of the Permit User script was optimized.
    TwitchLinkGuard-3.6.sb (23.4 KB)

v3.5

  • The script was once again completely overhauled to have a better reaction performance in some cases.
  • Removed the useless if/else logic since an optional group system was introduced long time ago. The script skips any moderation for VIPs and moderators since those roles are supposed to be trusted users.
  • Whitelist is now even more flexible and doesn’t require asterisks anymore.
  • Obfuscated messages with special characters are now fully filtered. Messages like “GĂŤt cheap Subs͢cÍĄr͜ibers example. com” is now handled correctly.
  • All default chat messages have been revised.
  • Protocols and ban reasons have been adjusted to provide as much information as possible about why actions occurred.
    TwitchLinkGuard-3.5.sb (22.8 KB)

v3.4

  • Fix: Somehow old code sneaked into the permit system that didn’t belong there and messages weren’t editable
  • Added more default detected keywords using special characters. i tried to add a automated detection for unicode patterns but i wasn’t satisfied with it’s performance, so you can instead manually add special character words to the %SuspiciousKeywords% list (e.g. BĚžuĚžyĚž, 𝑉𝑖𝑒𝑤𝑠, 𝓒𝓵𝓲𝓬𝓴, G͓̽r͓̽o͓̽w)
  • Removed some useless code actions
  • Ban reasons and respectively log messages now give even more details about why a user message was banned/warned/deleted.
    E.g. Posted an obfuscated URL along with a prohibited keyword: Keyword: 'nezhna', SuspiciousEnding: 'com'.
  • Code got some kind of a “structure”.
    TwitchLinkGuard-3.4.sb (24.5 KB)

v3.3

  • No touching the script to edit the whitelist anymore!
    • Whitelist now use the same system as suspiciousEndings/keywords but without a predfined default list, so if the argument is disabled/missing, no links are whitelisted.
  • Removed many TLDs (Top-Level-Domains) since they aren’t frequently used anyways (like .at) and focused more on commonly used TLDs appearing in spam messages
  • Fixed some typos again.
  • The isBlockedByTwitch System now bans users posting links with suspicious keywords instead of just deleting any message regardless.
  • isBlockedByTwitch is now removed from the KillSwitch System since there is basically no way of malfunctioning.
  • Removed “light” edition since main script is now stable enough.
  • Updated the Instructions.
    TwitchLinkGuard-3.3.sb (23.0 KB)

v3.2

  • Made myself more clear where to go with the script and ditched the idea of a “Spam Protection” that give the possibility of a delayed penality since twitch only deletes the last message with TwitchWarn and it just would clutter the mod-action list for no reason
  • Optionally, you can set useTwitchWarn to True if you want to give out a ‘warn’ additionally to users posting links in the TLG-Options Group
  • Refined the whitelist logic to be more dynamically and accept wildcard placeholder asterisks at any position in the link (e.g. *twich.tv, www.discord.*) so URLs don’t have to be strict.
  • Adjusted the regular expression used in the IsObfuscatedMessage function to be more flexible
  • Fixed many typos
  • Removed deprecated lines
  • Removed IsObfuscatedMessage function from Killswitch since there is basically no way of malfunctioning
  • TLG-Permit User now has editable chat messages

v3.1

  • Spam Protection is temporarily removed from release version since i was not satisfied with its performance and state at the moment.
  • The permit system got some enhancements and has now more configurations.
  • Added three “Killswitch” arguments if something goes wrong (which should not actually but who knows) for a certain period.
  • Once again some rearangements and added colors to make it more appealing
  • Updated the Instructions

v3.0

  • Sub-actions are now more clearly arranged and grouped.
  • All messages output by the script are now customizable in the “Chat messages” group.
    %suspiciousKeywords% and %suspiciousEndings% can now both be directly edited in the “Options” group, allowing the script to be more easily adapted to individual needs. Both options are disabled by default, with the previously known list serving as the default until the arguments are activated.
  • Spam protection is now fully optional, with all related functions grouped together (and probably took me more time and nerves than it was probably worth :D).
  • Spam protection can now be modular, specifying how many links can be spammed before an official “Warn” is triggered by Twitch. (Messages are still deleted and the user is warned.)
    • Also optional: %usePenality% allows you to decide whether a timeout or ban should occur if a user continues to post links after a Twitch warning.
    • The duration of the timeout or the alternative ban can also be set.
  • The script has been slightly adjusted and now shows where the “Touchy Zone” begins upon opening.

v2.8

  • removed the broadcaster if/else logic since it doesn’t make really sense
  • added more explanations in the new rearranged sub-actions and in the code
  • added more Logs to steps i thought they’re necessary
  • TLG now features an optional Spam Protection:
    • If a user spam more then 5 links (with non-suspicious text) twitch sends out an official “warn”, broadcaster and moderators can see in the users history
    • If the same user proceed to spam links, a timeout or ban occur based on your settings.
    • The argument %useTimeout% handles if a timeout or ban happens for Spam Protection.
    • If you set the value of %timeoutDuration% to 0 it will ban users.
    • Regardless of your above setting, a user will receive a official “warn” from twitch after posting 5 links that is tracked in the users history. So it’s easy to inspect warns/timeouts/bans for Broadcaster and moderators by clicking on the name of the user

v2.7

“Stable”/Light verion

  • Made the %groupName% argument optional and added SB’s own if/else logic again, to skip broadcaster, moderators and VIPs since it’s easier to implement. Anyway, you can enable %groupName% and add trusted users to this list for exemption.
  • Removed the %groupName% logic from the !permit Action since they are exempt anyways if activated
    TwitchLinkGuard 2.7.sb (12.5 KB)

v2.6

  • Added new subaction folder called “Options” with some QoL arguments to both actions
    • %groupName% now uses the predefined group TLG-TrustedUsers to detect if users are trusted to post links. You can edit the argument to user another group aswell.
    • %useBot% now let you decide if you want to use your bot(true) or broadcaster account(false) for messages and bans
    • %sendAction% now let you decide if you want to use SendAction(true) or SendMessage(false)

v2.5

  • Added a check using CPH.UserInGroup to determine if a user belongs to the TLG-TrustedUsers group.
  • Add a argument to use another group then the predefined TLG-TrustedUsers group.
  • If the user is in the trusted group, the script skips the !permit command and sends an informational message indicating the user is already allowed to post links.

v2.4

  • fixed an issue were the script would delete messages tagging users only with emotes
  • refined the obfuscation detection
  • script is now completely commented
  • permit messages are now completely in english
  • Still watch out for messages held back by twitch

v2.3

  • The script now detects messages flagged by Twitch’s built-in AutoMod feature using the TwitchDenyAutoHeldMessage flag. It denies these messages, bans the user and provide an explanation in the ban reason. No further messages are posted in the chat, as only the broadcaster and moderators can view these flagged messages. (Needs some testing since it’s not easy to test this alone, prepare for failures )
  • The script now exempts common bots from being punished for posting links (e.g. sery_bot) , provided they do not hold moderator or VIP roles. This exemption can be customized by modifying a list in the code.
  • Messages now have , true); at the end, so you can better decide if bot or broadcaster account should be used by using true for bot and false for broadcaster account.

v2.2

  • Detects now URLs that get replaced with *** by Twitch’s own link block system and warns the user to do not post links
  • Ban reasons are even more detailed now: explains why the ban happened and what keyword was used: banned by BOTNAME, reason: Posted an obfuscated URL with prohibited keyword: example

v2.1

  • Completely reworked the script
  • Way more robust script structure handling different Links in messages
  • Warnings/Bans are now explained afterwards and there should be no failures anymore
  • For everything else: please read the overhauled Opener for all Key Features
  • For people disliking sendAction i now added a “b”-Version using sendMessage

Seeing as the extension itself is more of in a “Testing” state at least looking at the Discord post and the amount of recent Changelogs, it might be best to first create a post in the “Testing” forums Testing - Streamer.bot Extensions, which should definitely be used before submissions if you know it’s not fully tested yet. That way you can also share the link from the testing forum with people outside, as the “Submission” forum is only visible for the people that created a topic and the staff :slight_smile:
