I didn't turn this into a vote because it's not something that people would have to vote on - it'd simply fix a problem in the game.
When holding ALT + 4 (shortcut key for /victory), the client's comp should only send the code if he can execute it. That means if you're in the air there's no reason for your comp to try to tell the server to make him /victory. Also, while you're doing /victory already or are proned on the floor then it also shouldn't do it.
In the past 2 weeks I have been flood-kicked (20 mins) three times for holding ALT + 4.
