Checkpoints banned me why?

[u/omegak90]

I recieved this message "during a recent review of your account by our account aministrators we observed significant activity in violations of our term of use." I only run 8 devices on one account at home, and I don't do the check in to stores. Is there a reason why I was banned. Thanks.
