yeah i see in game chat only fairfight ban xD but i used some hacks about month ago and i still dont have ban. Maybe you have been recorded by some spectator and get reported. I have noticed that so iam using cheats in limits (i dont have score 150/5 but i play smart and dont want to be MPV) and if you dont have been banned in the past then your current ban is not permanent and after 2-6 months they are give you unban but do not use hacks cuz they will be watching you for some strange activity on your account and then you will get permanent ban (one friend tell me premanent ban is on your IP so you dont have been allowed to play any copy of BF1 ever. =/
Thats not how it works. They ban your account which is linked to the game. Your IP has nothing to do with it, and probably is dynamic anyway. 10+ years ago games were like that.
