Two matches joined. Two bans acquired. This was because I killed the admin, and he in anger kicked me even though jets weren't forbidden.
Third server, Kharg Island Conquest. The only rule is that you can't shoot down admin's heli, or you get banned. Of course he whores the Havoc all the time.
If you're reading this and own a rented server, make us all a favor and make fair rules and don't kick/ban for nothing.
Addendum: Today I got a random jet kill by bursting the jet cannon for less than a second from 200 meters. Didn't even see the guy. Lucky me.
