If you try to access pages on ThisCrush and you're being redirected to http://www.stopbullying.gov/cyberbullying/what-is-it/index.html then you've been banned.
These bans are activated for specific actions that you've performed and they will not be reversed. Even if "it was just a joke". We don't consider harassment and bullying to be a joke!
A site wide ban typically expires in as little as 2 weeks, or could stay active for a month.
