Mmm, interesting how they are also pretending to be well known fantasians. (See Care's post that was mentioned by Cream; Antimony is mentioned there)
Maybe the same person who pretends to be 5 different people at once. When someone impersonates I do try and fish out some information. They are clever enough to lie to me about it.
But by saying that, they are doing a good job of creating a lack of trust within the community.
