The tl;dr for anyone skimming the comments: "CloudFlare doesn't like you" in this case means a gambling site that was getting CloudFlare shared IP addresses legally blocked by ISPs in countries where the gambling site wasn't licensed/was illegal. And "abusing low prices" means CloudFlare wanted them to pay for a bring-your-own-IP plan to give them dedicated IPs so their blocks wouldn't affect other CloudFlare customers.

Cloudflare was really unclear about their motivation was and it was effectively a matter of kicking them off for not liking them. CF was annoying them about an overpriced enterprise plan, before suddenly throwing out accusations that if true would have meant cutting the company off even if they did buy enterprise. And they were demanding a ton of money, much more than bringing an IP is worth.

Maybe maybe bringing their own IP would have solved the problem, but Cloudflare was obstructing everything and then did a cutoff without proper warning. It was really bad on Cloudflare's part.

This the same cloudflare that gets blocked in the entire country of Spain during every football match and says nothing about it?

They really hated that particular customer.
