Weird ban

So I was playing normal on farm running a shotgun with ap shells. I was at some point trying to find someone who was already fighting someone, found him as I was trying to get closer and blast him with the incredible ap shells I gor band for violating the rules. The ban is for 24 hours or less. Am I the only one who got such ban? Did I atcually do something wrong whatever it is. Keep in mind I am NOT a hacker.
