The problem isn't Google Safe Search backlisting the side (I mean that also is a problem, but a very different one).
The problem is the vanity domain registrar Radix using that as a reason to _put the whole domain on hold, including all subdomains, email entries etc._
This means:
- no way to fix accidental wrong "safe search" blacklisting
- if it was your main domain no mails with all the things it entails
- no way to redirect API servers, apps etc. to a different domain. In general it's not just the website which it's down it's all app, APIs, or anything you had on that domain
Google Safe search is meant to help keep chrome users safe from phishing etc. it is fundamentally not designed to be a Authority Institute which can unilaterally dictate which domains are no longer usable at all.
Like basically what Radix did was a full domain take down of the kind you normally need a judge order for... cause by a safe browsing helper service misfiring. That is is RALLY bad, and they refuse to fix their mistake, too.
You normally don't have _that_ level of fundamentally broken internal processes absurdity with the more reputable TLD operators (which doesn't mean you don't have that in edge cases, but this isn't an edge case this is there standard policy).
At the same time given the already terrible reputation of such vanity TLDs, being this hard on abuse might be the only survivable way.
That's not me saying there shouldn't be a warning and a recourse, but the time-to-profit for domain abuse is really short so anti-abuse actions have to be quick.
