Just because you are Admin does not mean you can:
Give your friends/yourself levels.
Give your friends/yourself money to buyxp.
Ban people because of personal reasons.
Unban your friends while they were banned for a good reason.
Heal your friends/yourself for no good reason.
Revive your friends/yourself after you get killed.
Use the amxmodmenu super menu for fun on players.
Blind your friends.
Burry your friends.
Slap/Uber slap people for fun.
Any admin that will get caught while doing the things above will get a ban and most probably full removal of admin.
