You are not on the current server ban lists. There is an expired ban from Rumblood(teamkilling) for you though. Try joining the official EU or NA servers. If it doesn't work, PM Meow or contact him on irc and ask if you are on the global banlist for autoblocking, scamming, multi-accounting or loitering. Incase of an autoblock ban, post in the autoblock
thread but make sure to read the OP first.
