Got banned on ARC TWICE falsely

I initially got banned from ARC raiders awhile back. I initially though it was the result of cheat engine being open (not being injected) in the background, but NOW the day I get it back I got banned again until April 3rd! This infuriates me because I had NOTHING open that time! I don't think it was because of any kind of software I had open and I can't think of any other code of conduct I broke. I literally played one 30 minutes match with my friend and then closed the game. Literally what caused this???
