Cloudflare has IP ranges all the way up on the Spamhaus DROP list. Cloudflare says they cannot control this.

Is Cloudflare in a "might makes right" position, or should someone be working to resolve the issues causing the SBL?
These are your only complaints with Cloudflare hosting?
I don't have a complaint. A customer brought this issue up, so I am just curious how everyone feels about things like this today. The customer feels one way since they pay Cloudflare (it's not me). I'm in the middle because I've used the DROP list for well over two decades as a border filter, before companies like Cloudflare were founded, but over time if the DROP list ends up full of "too big to care" listings, then that makes its utility less than what it once was. ~Seth
