alt Hacker NewsIs Cloudflare a cheapo VPS?
It is a cheap VPS, but it would still be nice if there was a way to know (not assume) beforehand.

Still blocked. The system is working as expected.

You can't have the cake and eat it too.
Either you use cheap infrastructure that attackers can buy by the bulk for sybil attacks.
Or you pay a reasonable price for a slice of an IP block that doesn't share its reputation with elcheapos.

I would simply like to point out that 550 at SMTP time is not a bounce.

Cloudflare is one of the shadiest hosts around, almost as bad as the big three clouds.
