In the video it's pretty clear that he was supposed to drown but instead he left via /q, Death evade does not only consider when you're being involved in a firefight, as soon you were caught in the act it will be punishable enough for it to result to a tempban, Maybe hunting felt that he will be heli killed instead he insist to drown himself in my view most probably but [ON]Hunting will be given a 5 days ban.
