If you try to find evidence that Cloudflare mitigates fraud and abuse, you'll mostly find anecdotal evidence (sites that have been attacked and moved to Cloudflare, mostly) plus information and claims provided by Cloudflare, which is unverifiable. The problem is that nobody protects us, the Internet, from Cloudflare.

Cloudflare will happily take money from and host (yes, host - they host, in spite of their rather stupid and completely disingenuous assertions that they don't) spammers and scammers. They do all the time, and they have no intention of changing that any time soon.

If you forward phishing spam to abuse@cloudflare.com, guess what? Nothing happens. You get an automated response, but they do nothing about it. They expect you to visit a web page that has all sorts of intentional problems (intentional because they've been pointed out to Cloudflare and Cloudflare hasn't addressed them for years) that make the process arduous and time consuming. For one, they don't have "spam" as an abuse type. For another, even though they now literally host web content, and even though they're a domain registrar, if you don't paste in a URL pointing to a site hosted by their proxying product, then you can't submit your form. This means there's literally no way to complain to Cloudflare about domains for which Cloudflare is in WHOIS and SOA records, and for whom Cloudflare hosts DNS. The fields are limited to some particular size (2,000 characters? I forget exactly), and have issues where if you paste more than a certain amount of content but less than the hard limit, you can't submit the form. If you try to use the form more than once a minute or two, IT'S RATE LIMITED and you can't submit the form. Imagine that - they need to protect themselves from human-speed abuse reporting.

In other words, it's REALLY hard to use their site to report abuse to them, and they know this, and it's intentional, unless we want to believe that they just suck at understanding how to make a web page that works.

If they get enough complaints about a given phishing domain, they eventually take action, but it'd be after several days, which is more than the lifetime of a typical phishing campaign. In essence Cloudflare is one of the most popular phishing and spam-promoted hosting platforms because of Cloudflare's intentional foot dragging and claims to want to "protect free speech".

They got on my shit list years ago when they told me - not kidding - that they couldn't just take down a Bank of America phishing site when it was pointed out to them because of "free speech". In other words, they don't want to set a precedent where they can apply the tiniest modicum of common sense and take down phishing sites which any reasonable human on the planet can unambiguously recognize as fraud.

Bottom line: Cloudflare tells the world that there's SO much bad stuff out there, and you'll get in trouble if you don't use their products, and that's mostly true if you want to run phishing and spam-promoted web sites, so scammers and spammers use Cloudflare and are protected from those of us who would report those spammers and scammers.

For all the companies and individuals who use Cloudflare, many are fooled in to thinking they need Cloudflare when they don't and are just making their sites problematic for much of the non-western world while helping a wanna-be monopoly re-centralize the Internet around a for-profit company that has a history of profiting from scammers and spammers.

If anyone thinks Cloudflare legitimately protects the Internet by mitigating fraud and abuse, I'd be very interested to see evidence that doesn't come from Cloudflare that shows this.
