I would make sure that anyone considering using njalla (and I have used them several times in the past, without incident) should know however that there have been many reports of people having their names jacked by them, due to the people having websites of ill repute, etc.

You can use porkbun, namecheap, I believe that internetBS also takes bitcoin. You should be able to use the first two (I use both of those registrars) without having to provide actual real information, aside from an email address that is valid and functional.

That said, one of the things that I have been wanting to build with bitcoin integration (and LN integration as well) is a similar platform to what njalla offers, however, fully self-custodied and without any third party requirement like they have. People should be able to sign up for domain names, email service, hosting/vps instances for example, from a site that you only have to connect to with your wallet and it'll use your keys for signing/securing everything, and let you pay directly there, while retaining anonymity and still be super easy. Could be run entirely autonomously.

As far as creating such a thing, the full implementation of this is a bit outside of my wheelhouse in terms of being able to fully have it functional in a way that I'd feel comfortable with others using (I could definitely do it and have it working, but some of the things required for setting it up are not my specific forte, so I would feel more comfortable working with someone else better at some of the backend stuff).

wow, I have a domain with them and I didn't know, thanks!

That's really useful! Thank you!

Yes, they do, I use it. And I think there are some other options too.
