He constantly ddosed his competition til few years ago and was a general douchebag. That's not the case anymore, in fact he hosts the most popular oldschool servers now.
I even reported him to the police once while he was ddosing me. He changed though, I even work for him now and even though it's in my interest to promote the server; I must say it'll be a really good one.
Give it a try, you won't be disappointed.
