We have recently had to ban a couple of people who were players we had already banned in the past trying to sneak back in under the radar. Often we ban because people engage in conversation that is completely inappropriate (as a reminder, you do not know the age of a player you are talking to, not for sure, not unless you know them in real life.) These rules are to protect our players, especially the younger ones.
Those banned players have been rebanned.
Please remember, if you find out that a player was banned and they come back you MUST report them. Rules state that if you don't, and we find out that you knew they had come back, you will be banned as well. It's not worth the risk!
