If at all possible, If someone is doing something wrong I would suggest being diplomatic(Nice) and warn before taking action. For instince, if there were a couple of hard targets out in the middle of know where, that I was having issues with, and I wanted to use a chopper forgetting to ask and Admin, someone notices and is not having such a nice day and takes away my flight privleges, I would be frustrated.
I realize that I am just a guest on the sparta servers, but if players have to be respectful and aware, so should admins.
Don't just kick because your under the influence or pissed, ask and find out the whole story beofore you take action.
just a thought
