Because You Broke The TOS
"Because you broke the TOS" was originally used by Message Board Help trolls in response to topics made by many users asking "Why was my message moderated?". Over time, as many users began to dislike it, it became used in a less serious manner but still continued as a joke. Now it is used in a similar fashion to Because You Touch Yourself At Night.
It was started by a lesser known MBH troll, ElectronicLink, who is now known as MikceyMouseRage.
