Forum:ID theft?

hi there, just found this site. My kids have been being banned lately.....they say it's not their fault, but it's a little strange. My daughters penguin had a three hour time limit. She was only on 43 minutes according to the connection history and was booted off! My son's ban history is clear, but yet he is also banned for another 44 hours. Could someone be using their penquins? Believe me I know my kids COULD be "swearing and bullying", but they are just so shocked by the bans I think they really DIDN't do it. Any other problems with this?
