I've been instagibbed a handful of times by him in infantry play, I suspected he was laggy but not a full on lag switcher.
He's a special kind of scum, knowing this now I'll be sure to piss him off in any way possible that I can, taunts, bounties, pulling direct counters to what he's driving/flying/doing and so on... that is only if I encounter him though, not going to go out my way to look for him, probably bannable and I'm not that much of a dick, I hope.
