Yes, but everything is abusable. Bot Events, admins, default events can be too, also votekick, console commands...
The list goes on.
As I a have not heard that excuse before, there is just some things that can break the game and the fun for others if used in a bad way, why do you think some admins disable events for non admins, and thats exactly why bot events where failed and added to the CRC/Crap ons list, nobody uses votekick anymore for that reason, I think you mean Eval on the last one, if so Eval is Super admin only.
