[align=center]What is Cloudflare?[/align]
Cloudflare is a massive global Internet security and infrastructure company, providing CDN, DNS, DDoS protection, and website security. They serve over 12 million websites, have successfully headed off some intense DDoS attacks, and until recently with the 8ch deplatforming, were quite infamous with the MSM and leftists in general for providing their services to le ebil nahzees, which included The Daily Stormer up until 2017.
As for what their alphabet soup of services actually does, I'll try to explain it as simply as I can for the non-technical among us:
[align=center]CDN - Content Delivery Network[/align]
Traditionally, your browser connects directly to a site to download videos, programs, images, scripts, et cetera. mlpol.net does this. A CDN takes over the job of sending all of that data so the actual website itself doesn't have to, acting as the middleman between the website and your browser. CDNs often bleed over into providing security services, as Cloudflare does.
[align=center]DDoS protection[/align]
If you've ever seen a website checking your browser to see if you're a human before, you've encountered Cloudflare's DDoS protection. Again, Cloudflare acts as the middleman between the site and your browser, and with Cloudflare's massive global network of servers, that means they can soak up all of the Internet traffic a DDoS attack creates, protecting the site.
[align=center]DNS - Domain Name Service[/align]
DNS is what translates website names such as "mlpol.net" into IP addresses such as 158.69.26.54. It's a very important part of the Internet, and everyone uses it whether they're aware of it or not. Your ISP runs their own service (which you're probably already using, and is almost certainly terrible), Google runs their own service (8.8.8.8, 8.8.4.4), and of course Cloudflare also runs their own """privacy-first""" DNS service (1.1.1.1, 1.0.0.1). This is important for reasons I'll describe later.
To get an idea of just how far Cloudflare's influence has reached on the Internet, this is just a very short list of the sites that use Cloudflare's services:

And that's just as a start.
You can check for yourself if a site is being served with Cloudflare by putting it into a DNS lookup application, such as https://www.robtex.com/dns-lookup/
Every site using Cloudflare services in any capacity is listed in alphabetical order at https://codeberg.org/crimeflare/cloudflare-tor/src/branch/master/cloudflare_users/domains
Also, their "Project Athenian" promises to provide all of their services for free to the United States government's election and voter registration sites.
They're also offering a freemium VPN app called "Warp" now.
[align=center]So, what's the problem?[/align]
Multiple things. I think it's fair to say that about 90% of you know all about the 8ch shutdown. This 'takedown' happened because the 8ch.net domain was pointing to Cloudflare's servers, and when Cloudflare stopped serving them, your browser couldn't find the site. In theory, it could have been put back online by the owner without Cloudflare at all, but he chose not to. I'm also fairly certain Cloudflare's action was a breach of contract as well, but that's pure speculation on my part, so don't quote me on that.
The real issues with Cloudflare, however, are a bit more widespread than just site takedowns.
If you're using Cloudflare's DNS services as above, certain sites are flat-out unavailable to you. Archive.is, when resolved by Cloudflare, is inaccessible, instead redirecting to 127.0.0.3, a localhost address that is never exposed to the Internet.
If you've noted the instances where I say Cloudflare's services act as middlemen between you and the websites themselves, this also presents another possible vector of attack:
https://en.wikipedia.org/wiki/Man-in-the-middle_attack
Cloudflare must necessarily be the middleman, so in theory, at any point, Cloudflare could modify anything you see on a website it is protecting. Using HTTPS does not protect you against this, because Cloudflare re-encrypts the traffic using a trusted HTTPS certificate that your browser is all too happy to accept.
Cloudflare, like Google, also provides lots of analytics and tracking capabilities for those using their services.
Amusingly, back when Frederick Brennan (Hotwheels) was running 8ch, any complaints that Cloudflare received about 8ch were forwarded, along with full names, email addresses, and IP addresses, to Hotwheels. Hotwheels then posted these details online. So, if you reported 8ch for any reason, you've been doxxed. I can't help but chuckle at the poetic irony of 8ch's takedown now.
Do you use Tor? If you've ever had to resolve a CAPTCHA over Tor, or on an .onion site, your anonymity is gone. Or, more often than not, you simply cannot access the site at all. This includes both Google ReCAPTCHA and Cloudflare's bot detection. Oh, and Cloudflare actively checks Tor's public exit node lists and blacklists their IPs, and does the same for VPNs as well. Better drop that anonymity if you want to visit our sites, goy!
TL;DR: Cloudflare is the devil, and anyone who uses it deserves whatever happens to them. 8ch paid the idiot tax. Don't be like 8ch, roll your own damn DDoS protection. Tell sites using Cloudflare to stop using Cloudflare.
