Not a good look for these "privacy" focused players.
I use AWS Route53 and Google for domain registration. Despite being "invaders" of privacy supposedly, so far they've done a pretty good job keeping my data from leaking - nothing too interesting anyways but.
One worry would be employers or others taking lists like this and doing some screening of candidates etc through it.
