I had a really bad experience with their domain registration system. It doesn't let you set up different billing addresses for each domain. I have my private domains and my business domains. Unfortunately, it wasn't that obvious, and I had the impression that I am able to set up different billing addresses. Turned out that I just always overwrote the last billing address. They refused to help me set straight the invoices for my business and for my private donains. Their UI failed me (it is really bad and not intuitive in this case), this is such a basic feature. Support was also not helpful. Overall it was a very bad experience.

They also have authenticationless DNS offerings

I was subjected to an attempted (and partially-successful) domain hijacking a few years ago

For several days, everyone who used Cloudflare as their DNS resolver had a scam site respond to my domain

Actually I had a similar experience with trying to create a business account, only the account who created it can set up billing. There is no concept of a team account or billing managers which surprised me.
