It appears the site you mentioned is running Google Ads. You can exclude your Google Ads from sites you specify following the steps of this article.
I used that domain name as an example.
The sites are pornobest.su and rumanba.com, warning NSFW.
I suspect scans for exploits from these domains.
I just need a way to block them from further access in website builder.
I suspected as much, I'd scoured the settings thinking I'd overlooked a setting somewhere.
I'm going to hate turning in this report to the clients.
Guess I'll be looking at other solutions.
