.I've Been Banned From Posting On The Forums - What Now?
Being temporarily banned from the Forums means that you have broken the rules or have not been participating in a constructive fashion. Take a break, go for a walk, have a snack, play some games: it's not a big deal. We're not mad at you; you just need a break. Please, take time to review the rules and guidelines as posted above.
A short-term ban is our way of preventing further disruptive behavior and asking you to reexamine how you behave. Do not discuss your ban on the public forums or ask your friends to post about it for you. That could get your ban extended and may even get your friends in trouble, too. Keep in mind that discussing moderation is against our rules.
If you think you've been banned by mistake, get in touch with our Terms of Service team by following the steps outlined here
