EagleOne, I use Ninja Firewall inside of UNA to help stop bad actors. I mainly use this to track our own ads we publish for affiliate platforms to track ad performance by an ads team. I am thinking that one way to stop someone from abusing this, is to make sure that everyone allowed access has their IP address in an htaccess file, and hence, no one that is not allowed in will be blocked. Of course, that is a little work added to the idea but one way to control things. I will try to find your post about this.
