I write a lot, and I write stories for friends, they pay me in pirated games, one wish was BF2, soon after everyone had a cracked version of BF2 running on LAN. Only problem was that if you TK'd someone enough times they would get booted while the teamkiller could get away with it. Tradition is to plant C4 on a friend's plane if you can't have it, and since we had spawntime 1S it became a bloodbath.
Same day, my friend was in an F35, me in a Mig was a lot faster and a much better pilot. I jumped out of the plane as it went straight forward and crashed into him.
Also going over to the aircraft carrier, planting C4 all over, then detonating it as the opponent takes off is also quite unsporty.
