One of those things that Cracker listed can occur if you have a bot that has a high ban risk so it should be used a limited amount of hours to stay on the safe side. If you were ever to bot, I would recommend paid bots because they less flaws than the free ones.
Thanks both of you.
Another question, if I'd never been banned or warned or anything, would I just get a rollback of stats? And how much would the rollback be, reset to 1 or reset like 5-10 levels depending on your current level?
