Cloudflare's rather shitty abuse reporting web form is broken now, too, with this error returned after a minute after submission:
An unknown error has occurred and has been logged. We apologize for the inconvenience and we will fix the problem as soon as possible.
They don't accept abuse complaints via email, and now that I'm getting more phishing spam hosted by their hosting service "r2.dev" than all other phishing combined, this is a real pain in the ass.
Cloudflare really don't care about abuse, do they?
