... Stealing members? Was he advertising on the server?
I was not the one who made the choice and from this point on I will refuse to answer questions about this matter because I just never experienced first hand most the things "he did wrong", but I can answer this question.
Nosliw himself did not specifically advertise his server here, but there has been a number of people who have advertised his server, one of whom who was perma-banned for other things,. Most of the ones I saw was when I was a user, did not screenshot in time, nor did I believe the ip they gave was real (which sadly now I know it was real.) Some people may have said there is an "advertising conspiracy afoot" which I have no clue if there is.
