Oh, no problem. Some people misuse it on these forums, which is probably why you had the wrong impression.
Griefing only has two requirements:
1) The person must be trying to frustrate/upset/irritate another player.
2) The person must be using a game mechanic in an unintended way.
Most people get pissed off when they lose, but the second part is why "winning" and "griefing" aren't the same thing
Sabotaging cooperative missions, and driving backwards to hit other players in races, are both examples of griefing in this game.
Alright thanks for that. But I tried to upset her, so it must have been griefing like you describe in point 1, not?
No problem. And it must be both 1 and 2, not only one of them.
...driving backwards to hit other players in races...
surely you jest
No, of course not. It's one of the most well-known forms of griefing across all racing games. Why?
if there was such an occasion where you could not get someone to stop killing you even through asking kindly than the least you can do is report them for griefing.
It's people like you who cry wolf at nonsense that prevents the reporting system from actually working. They should define the word "griefing" on the report form, for those such as yourself. I'm sure they never imagined there'd actually be people who would voluntarily purchase and play a game with nonconsensual PvP and then somehow think it's griefing when someone kills them more than once.
That's the game you're choosing to play. If you don't like getting killed repeatedly, don't play shooters. That's sort of what happens when you're bad.
