@S_B_2_Go, let’s put aside the issue you are addressing for the moment.
Any filter you set up against me, I can sit here and think of a way to get around it. If I’m the rickrolling type, I’ll get my video links and lyrics in somehow. Maybe I’ll take a photo of the lyrics, or I’ll share an ASCII version of the video. It will be weird, it will get through, and I’ve got all the time to do this.
If there were, then we’d be pitting humans thinking up silly ways to rickroll folks and the plugin would take so many evasive actions eventually it would interfere with the operation of the site; meaning now it’s affecting people more than just annoying topics being published.
Hence this sound advice:
Okay, turning back to your specific case, I noticed…
This sounds like you and the mods have an opportunity to discuss this with the admins in your community, and address it together! 
If you are having trouble with a few users, talking to your team will provide more perspective, as well as more tools to use that already exist. And if it is many users, then maybe they need a place to be silly, and the admins need to know about it. In any case, you can work with your community staff to assess what, if any, technical solutions you need to apply.
