This poster "M" was going around putting everyone else's names on posts that he himself was writing. What I am guessing is that "M" signed a post "Ana" that was not too nice. Then Lady Bloom did write an actual post (she signs her name Ana) that John C. thought was "M" again.
I don't know that for sure, but I think that's what happened.
Anyway, "M" is now gone and we will now move on to the next problem. Ha!
