I...won't lie, it sounds like it *could* be the case - but I'd be hesitant to say that since 1. It could be that they really id that way, and/or 2. it's possible that it'd set you up as a target.

Either way, what they're doing [abuse, doxxing, etc] makes it sound like they're a real piece of work, OP. Sucks when someone like that becomes a BNF.
