>>714810747Shadow Bans have been a thing at least since Cold War, possibly since MW2019. In short, the moment you get X amount of reports on your profile, no matter for what reason, you get shadowbanned, and can only play with other shadowbanned players(mostly hackers). There is no recourse for this, Activision doesn't manually oversee this process and you will only get unbanned after a few weeks automatically ,or if you're lucky if you manually call the Activision support line and request a human janny to "speed up the process" because you were wrongly reported, and even then there is a chance that the jeet on the other line will tell you to fuck off because there is nothing he can do(read: he is too lazy and won't bother).
Mass reporting has been done by both jealous shitty players to "punish" people better than them and cheaters who mass report players with bots like you said for years. There is nothing you can do about it, if you play COD now you just accept that you can be banned, shadowbanned or proper banned, at anytime, temporarily or permanently, and there is nothing you can do about it, doesn't matter if you never did anything wrong. Of course, cheaters don't care since they will always have ways to avoid bans or simply wait them out, they have entire schedules for when they're going away and play on different accounts in the meantime until those, too, get banned.
Playing COD now is a job in and of itself with all the grinding and all the exploits you have to do just to not get into SBMM heavy lobbies anyways, if you played these games in 7th or 8th gen you would never recognize the absolute open sewer they have become now.
BTW I recommend Blame Truth on youtube if you want to see just how fucked up things are getting day by day, he's pretty much one of the last few old COD youtbers from back in the day and he's only making videos out of spite, nobody else is really reporting on this except for Nero.
