no its not that, its reports, i have been shadow banned on multiple accounts never permanently banned, people literally say in chat 'reported enjoy your ban' few games of people like that in one night and im shadowed again, i built the pc with new parts, if it was a case of hardware was banned account would be perma banned after checks. i have done plently of research as been getting the issue since november when i got orion camo people instantly thought i was cheating because had it after 1 month.
a lot more people have this issue im pretty sure majority that complain about it are likely not cheating however i agree there probably are a few that are.
