Does the in game reporting even have a function to report. Doesn't seem to go under any category. Kind of impossible to put under harassment when there are no comms to enemy squads.
It's community interpreted but it is someone just crouching up and down. They don't take their trousers off, so visually just a motion.
Some finishers animations are designed about mocking anyway. i.e. Fuse finisher "Helping Hand" where he pretends to revive you, winks then smack you down again. So that's designed to mock another player.
Lets say someone strafes left and right whilst shooting a box. Would that be interpreted as rude as well...
What about jumping up and down on a box or doing it next the box so it's indirect.
Eventually ban based on mocking a death box in any shape or form due to interpretation from internet or how another person perceives it...going a bit far. EA going to review every video footage sent? That's thousands of clips a day.
Far bigger problems. The toxicity isn't from enemy squads, it's comms from own team mates who seem to have personal issues.
