Some people in the lobby reported Brabus to the blacklist just because FTS said on stream that Brabus is a cheater. I'll add him to my blacklist too...
There used to be a player in the lobby with the nickname Zloy or something similar; he did an analysis, and he was banned, but you don't do any analysis... you're just being unreasonable. Although, of course, it's great to think everyone is stupid; it makes life easier.
