i mean, good point on the project size, but buying a domain is honestly such a basic thing that it still feels like a weird result on that equation to me. for fmhy.ml, specifically, i understand their choice, since pirate sites do tend to be quite nomadic with their domains, and the fediverse being so domain-specific is a new thing.
still, domains are hella cheap. the $10/yr figure i quoted is for a “serious” one on one of the major tlds, you can get away with much less if you’re willing to go for a somewhat more niche but still reputable one. especially one that’s longer than two characters.
