A lot of the mods for big providers like FB require counseling after the horrible crap they see (not just CSAM, but also terrible things like animal abuse and mutilation, etc). Unfortunately, the big companies have outsourced much of it to other countries where there aren’t as many worker protections, traumatizing people and replacing them when they can’t meet some arbitrary metric.
I’ve been using CloudFlare for my DNS registration. They’re incredibly cheap (I think they sell at or near wholesale rates).
For hosting, I tend to use Dreamhost. I think that it’s about $100/yr, with unlimited email inboxes, unlimited bandwidth (no porn or video hosting, or other things like that in the TOS).
Personally, I use Fastmail for my email (and CloudFlare’s email forwarding to forward to it), although Proton is pretty good to look at as well.
