After the report on you, I checked and compared with the logs. There I noticed you were only taking a fraction of the damage you should normally receive. It would happen in periods, there were long periods of you taking normal damage, then at one point switching to another period of taking a fraction of the damage. From the logs, we also see the damages suddenly returning to normal after you were reported on the forums. So, we can pretty clearly see you were using damage mods.
Please remove all of your mods, and you'll be unbanned on 21 February. Do not join the game anymore until it says here you're unbanned.
