Mods <-----> Owners
Only Owners can ban indefinitely. Mods can ban users up to 48 hours. If there is a user that should be permabanned, contact an owner and provide the basis for permaban.
I talked to Donald recently, and he said that punishments for ToS breaks are for users, not for accounts. Meaning users can ban ban evading alts, but the bans cannot be extended for ban evasion.
