I didn't like my first online coop experience either. Some jock sounding person was yelling "fucking idiot! you are a fucking idiot!" at me because I didn't instantly save him from a hunter after he ran ahead for miles. Then he tried to have me banned, which luckily failed in the voting. Finally, after my infected kill score was about 200 over anyone else in the match, the guy told everyone to "let trubinator die" during the finale, leaving me dead on the ground as the plane took off. Nice community...
