there validation system is very slow, just relax you will get your activation code within a few days, or you could try going on thier IRC chat and get one of the admins to activate your account!
I just made an account yesterday, and I was fine.
Do you need the account for the download link, or to post? If it's the download link, pm me and I'll give it to you. If it's to post then wait, and if that doesn't fix it ask on their IRC Chat.
im having same problem, i had an acc couldnt log in amde another 1 they didnt send a code and i cant connect to there irc chat =S i have been with rsbot since the start and now its gone =((((((((
