Only tangentially related, I'd warn against .icu, .xyz, .tk, .online, and if you aren't doing business in these regions, domains associated with russia, ukraine, china, singapore, taiwan, bangladesh, zimbawe, and south africa. Many problem sites have been hosted on these domains, and blocking them is such an effective mitigation strategy it's surprisingly common. It can be difficult to for example send emails from these tlds, and firewalls may block your site as harmful, search engines will ignore you or penalize your ranking, etc.
