Yep. By linking your account, you agree to have read the rules. However, to most people that's just a button. You push that and you get to play. That's why we have staff, to take care of those who don't want to read the rules or abide by them.
Also, yes, all players are held to the same rules. (With the exception of one or two for Staff purposes.) Being a donator, Helper, Moderator etc. does not make you invincible from the rules, and each member is held accountable for them.
The only real exception would be Broonie. He may do whatever the hell he pleases.
