Website privacy

I want to make an online community, but I don't want the users to be able to dox me. What precautions can I take to stay anonymous?

There's basic whois stuff (so I can just use DomainsByProxy or something), but what else do I have to worry about?

Very funny. But seriously, what should I do?

I am just concerned about people either hacking the site or being able to socially engineer the domain registrar to get my personal information.

I've heard about people's phone numbers getting stolen and transferred to some other phone (allowing the attacker to reset their passwords on SMS 2FA accounts) because they called up customer support for the carrier (such as Verizon) and then convinced them that they needed the phone number on a new SIM card.

So basically I am wondering about which domain registrars are best. Like, they won't get socially engineered into giving someone my info out.

It will be a law-abiding site, but I am anticipating that there might be trolls here and there who will try to mess with me.
