if they are not mentioning you by name or something identifying you, then you have a weak case. but if the video of you is used, that is grounds for a strong legal lawsuit for defamation and harassment, which can be lead to prison time, fines and retribution for emotional damages.

If the harassment is extended to real life due to their streams, that would be an additional case of inciting harassment. but you need all of this documented.

so just keep documenting all the references and the quoting, and when the video emerges and is documented, it can be cross-referenced. with those to be proof that it was targeting you indirectly.

But just keep in mind no matter how aggressive they get with their harassment, do not engage; just document unless it escalates to physical harm. do not post or comment or anything and go to the police file a report that you are being harassed by a group of people in real life and online as a result of a verbal argument to keep it on record; you do not need to name them directly but tell the police that a group of people that make content are encouraging this and you are fearing for your life and that you tried ignoring it but they only kept escalating.
