Sludge pool banned?

I won a few slag games and then the sludge pool was banned... Am I missing something? Slags suck and I was running them for fun. Was this an ongoing problem or did I get slags banned by winning a few games? I have been away for a while so I am wondering.

not worth explaining, he knows this already, how else do you think he got the wins.
