[2021] Banned for 7 days because one of my teammates ran in by my c4 by accident.

I was playing casual with one of my friends when we got to the last round. We were defending on house and i was destroying the attackers drones when I missed a couple of bullets on one of them. The drone then stopped and stared at me so I thought it would be funny if I killed myself with a c4 for missing that many shots. When I threw the c4 on the floor I quickly checked that i was at a safe distance from my teammates but when I detonated it one of my teammates ran by my side, but when I realized he was there i had already pressed the button. Note that this guy had been afk for the entire prep phase so I didn't think he was gonna start moving then. Now, i already had reverse ff active because in the first round one of the defenders jumped out a window and was chilling with us but one guy from my team killed him so i shot a couple of hipfire shots with the intention of lowering his health but i got the reverse ff thing. I had already been given a 24 hour ban for accidentally killing the hostage I would like to add that my last 3 bans have been for accidental tks. I reached out to ubisoft and they told me that there was nothing they could do to revoke or reduce temporary bans which is just ******g dumb. They should add a system where the whole teams gets to decide if you can stay or not kinda like the old vote to kick system we used to have, or they should be given the ability to revoke/reduce such bans.
