There is also one tough thing called hardware ID ban. The only counter to that is having a spare notebook/computer. If combined with IP/subnetwork ban, it will be very hard to trick.
Though I'vet yet to see a hardware ID ban on forums. Only in online games.
I had an account permed just for saying I was going troll the site and do nothing else, but that was a joke. I guess asking questions later is the best option eh mods?
For those of us with accounts we'd like back. I was thinking it could be like a once a year thing, that way members with permanent bans still have to wait at least a year.
