alt Hacker NewsSure but that doesn't really work with the existing age verification laws. Unless .xxx is requiring domains to implement age verification or there's some sort of global redirect to a verification portal, that site is back in the same legal jeopardy of having Texas confiscate their domain again.
The article in the comment I was replying to wasn't talking about age verification laws, they were talking about "parents protecting kids", a.k.a. content filtering.
As for the other part, I'd just assume that they wanted to switch to a registrar more used to adult content websites and less likely to be impacted by the Texas govt. Just like pirate sites switch TLDs to the ccTLD of the country least likely to prosecute them all the time.
I was mostly just talking about the fact that registering a domain with a registrar that is about "XXX sites should help empower parents to keep their kids away from adult content" isn't necessarily a bad thing.
