How can there be io overuse without a website?

I think your account gets buggy, just like mine before. I never got any I/O issues after moving my entire websites to another account. Maybe you should try moving your site to another account?

My account keeps getting suspended for no reason

I had this problem too. Eventually, I just transferred all of my websites to a new InfinityFree account and the problem was solved, I was no longer constantly getting suspended for IO. What’s strange is the old InfinityFree account that I transferred away from kept on getting suspended for IO limits, even though there was nothing on there. Try doing that and see if it works.
