Does your auto clicker have break blocks on?
I have noticed a lot of bans too. if you appeal it, they give you a more specific reason in the deny message
I was using auto clicker 7-12 random, reach 3 to 3.2, velocity 94%, name tags, ESP, and aim assist 3.2 at 4.2 distance so I don't know if it was one of those that got me banned
