Advertising is punishable by ban.
Hacks are punishable by ban, ban hammer gives no mercy even if you are mentally retarded or have a life threatening disease, if you hack you will be banned, who cares if they're new? They took the time to find and install the hacks so what makes you think they'll remove them?
As for Donors? This has already been discussed, you don't have to duel them, they used real money to be able to use those commands.
Just say no to the duel.
Support class should not be abusing those commands in duel, report those players with valid proofs and action will be taken against them.
