This is not a once in awhile problem. I get spam every single day without fail and every single time the spam links track to and are protected by Cloudflare. When it’s very clear someone is abusing your services for this reason why do you not terminate their service? Oh it’s nice that you will ‘forward the complaint’ to the host when you should tell US who that host is so we can take it up with them or better yet since they are clearly abusing Cloudflare services that you terminate their DNS services and stop protecting them. There is no easier to use tool to get away with non stop spamming and scams than Cloudflare. Why do you operate your company like this which only aids the scams?
