Rick Roll Detector (Blacklist-Based)

[tkgo11]

Describe a related problem (optional)

Users are frequently getting tricked by "Rickroll" links in comments, chats, or shared URLs. This disrupts productivity, annoys users, and impacts trust in shared resources.

Describe your suggested feature

Add a detector that flags or blocks suspicious links known for Rickrolling by comparing URLs against a maintained blacklist. When a match is found, the system should:

Warn the user before opening the link.

Optionally block access and show a custom message.

Allow admins to update or extend the blacklist.

Describe alternatives you've considered for your suggested feature

Heuristic detection (analyze video titles, etc.) — more complex, may cause false positives.

Other details

The blacklist includes full YouTube URLs (e.g., https://www.youtube.com/watch?v=dQw4w9WgXcQ)

And... don't take this seriously :)

Not sure if joking or not 😅

In any case, I think a full module to detect rickrolls is unnecessary. A more generic system may work, but I think with the current tools you can already detect links.

In fact I have this on my personal patterns list, perhaps I can add it as a default? 🤔

 "Rickroll": {
    "regex": "^https:\/\/www\\.youtube\\.com\/watch\\?v=dQw4w9WgXcQ"
  }

The ability to update the patterns based on a external repository is something that was discussed, and I find that useful, but will require changing a good part of the internal format, and honestly I don't think it's currently feasible (I think Pablo already made some progress though)
