My account has been banned

Hi there,
I have a problem. My account has been banned for cheating even if I haven’t play warThunder in the past 10 months or even more. I would like to know why cuz I play this game from closed beta and I have never cheated in any game. BTW my last games if I rememeber correctly were preety bad so I really don’t know what’s happend. I from poland I play on my PC that have the same IP from like 2013?
If someone cheated on my account I’m not sure how he get access to that cuz I have 2 step verification with gajin app on my phone.
Maybe that was some mistake? Please help me if u can.

If you have cheats on your PC for other games, it is possible that Anti Cheat has recognized this and has therefore banned you for having clients on your PC

But I dont have any cheats to be honest maybe some mods for RTS games but thats it
