Cloudflare isn’t anywhere near being the second worst registrar. I’ve never had anything remotely similar to this occur, and I’ve had hundreds of domains with Cloudflare for years.

Cloudflare will call you up one day demanding an immediate payment of $150k and holding your domains hostage if you don't comply.

Yeah, thats FUD. Cloudflare hasnt called anybody demanding huge sums of cash and holding your domains hostage. As a registrar they're fine, dont play scammy scum upsell games (because they have a real business model that isnt just registration skim).

For me, it's Namecheap.

That's worrying. My search-fu is failing me. Link please.
