She can only "rope you in" if you let her. She's just an attention whore trying to get a rise out of you. put her on ignore and she'll move on to somebody she can get a rise out of. She doesn't care if it's negative attention she's just fighting her own worthlessness.

Ignore wont stop her from starting her own threads or replying in threads that other people start but if you don't see them anymore, who cares, right?
