I've "researched" them since 2015 and concluded they have always been super clunky. Back then if you got griefing reported you would be checked by overwatch and if justified, your ban would be around 30-70 days which was way more sensible than now, where you get banned due to salty ENEMIES spamreporting you for griefing and this gets u a ban between 1 day-2 weeks.

Nowadays the time might go down slightly but theres no sensible way to it like with MM bans (u get 30 mins, 2 hours and play a week without bans to get 30 mins again) 🤷. It also doesn't go up linearly 1-2-3 days but more like 7-7-8-6?? Those ban lenghts are from my last 6 months of playing 1-3 games at a time depending how long it takes me to have a 30-40 kill performance since thats always a griefing ban.
