Shadowbanned but not shadowbanned?...

Im soo uncertain to what the hell is going on for me and shadowbanns, So to be clear i have to reinstall windows and change my mac every time to get around playing on a new account without my shadowban, maybe like 1 and a half weeks ago now i was shadowbanned on my main because i updated my internet adapter drivers and i forgot to change my mac etc so that account got the 350ms ping thing, waited like a week without even thinking and i got my friend to log into my account to check to see if it was still shadowbanned..and the ping for him only went up to like 90ms, he has shit internet also which might be why queue times are long.

the thing is my computer has had a new cpu, new mobo, new ram, new nvme, i don't want to get my new parts blacklisted but what is the best way other than buying a spoofer to check to see if im good as i still wanna use that account?

thats a good question,wish i could help.but i think there is no way,because this is why blizzard do this i think.
