I gotta say, I really like Karlotta - even the rage. He/she swims against the stream without fear of getting judged by the masses, and that's a positive trait to me.
I don't know the backstory, been curious about it too. Someone said hacking, don't know if it is true. I do think admins have shot themselves in the foot a bit by having a bit of a laugh through that Karlotta alts ban list - it makes people like me, who aren't privy to information, somewhat suspicious of the whole thing. When the bans were done silently I had no clue about Karlotta, but on the other side transparency in the administration is a good and much needed thing too.
