why will this happen? I always play by the rules, and suddenly the account was banned, amazing! This is entirely a misunderstanding, GM hopes to help look at, thank you!
Gamemasters are currently very busy and there are a lot of open cases. They do reviews of bans, forum moderation, ticket support, etc in their freetime.
That means, they also have a reallife and a real job which they're giving priority to.
Be patient and wait for a gamemaster or admin to review your case.
