(Note: I intended to put this on the official DU4 thread but I can't seem to find it since the forum was revamped.)
An admin from DU4 might want to check the server log for the (N5) HeavyMetal 32-Heli server on 12-31-2014 between 5:00-5:30 UTC
so this griefer idiot can be perma banned. He was repeatedly destroying his own team helis at the Russian base by parking a tank on the heli pad. He did it several times while I was on the server and I took some screenshots for proof.
(It was lagging me so bad while I was watching him that I was afraid he might crash the server.)
