This seems like a very messy area, with several related posts here but nothing solid. I don’t know why but they all seem kind of dodgy.
Besides offering WHOIS redaction, the most important thing for me is that I can trust the company won’t accidentally leak my personal information, or perhaps intentionally share it, sell it, or be hacked.
I think an EU based company would be ideal because of GDPR. And ideally something which isn’t “Big Tech” (Cloudflare?).
I was almost sold on Trustname which has been recommended a lot here for being a privacy-focused registrar, until I realized it was the same person repeatedly mentioning it here and who is likely affiliated.
Searching this forum, its just 1 person repeatedly mentioning that registrar so highly likely a shill thats affiliated with them. Be careful out there with those so-called “bulletproof” anything.
