Under what circumstances do you grief? I'm talking about teamkilling, being useless, and helping the enemy. This does not include doing random crap like using a crappy weapon because it's funner to use than other guns, (I consider that griefing but I'm leaving it out of this conversation), roleplaying, cheap tactics, and spamming messages in text or through the mic.
And because several people will ask about it: Griefing is where a player forsakes the general rules and screws around, almost always at the expense of his team.
