In relation to their threats to expose you on AB - If you have evidence that clearly contradicts her statements then you've nothing to worry about. Warnings that are put on here without clear evidence are quickly shot down - they're not just taken at face value of "this artist ripped me off" with nothing to back it up.

I'm curious though, though you don't necessarily have to say who you are, you can remain anonymous, would you consider saying who you are complete with evidence of the actions against you? Even if you made a journal addressing it, it would clear your name against the allegations.
