This is a fair point. I guess it's the sort of thing that I'd prefer to see fixed with a double-check prompt instead of a rejection, but I doubt it's causing many problems. I was primarily thinking of short domains like "gmail" and "aol". For those, I can see a company called, say, "Gail" getting blocked from legitimately using "Gail.com". "Hotnail" seems a lot less risky. Not a big problem, I just have an aesthetic objection to very high-friction things like blocking possibly-legal domains. As a double-check option I wouldn't object, and in fairness it's possible no one has ever been inconvenienced.
