Best is to just speak with their support and ask them directly, you could also contact shinjiru - i have used them in the past and they dont give a fuck about dmca (don't know if they allow adult stuff, but I think so).
Make sure to use a VPN (or even TOR) with Protonmail to register everything. Pay in crypto that is not bought with your real life credit card (or similar). For the domain, check out namesilo or prokbun. Consider using cloudflare as a rev proxy. Best of luck!
Whatever you do, avoid njal.la at all cost, they will scam you at some point!
