I’m not disagreeing about the result, Lemmy definitely feels less spammy/trolly, but either you or I have misunderstood something about registration. As far as I’m aware, any rate-limiting, proof of personhood, email verification, etc. is completely a per-instance thing. So all you’d need is an instance that’s permissive to get heaps of accounts. Or even if there aren’t any permissive ones (that haven’t been defederated), you could host a private instance, or sign up on multiple instances. However permissive Reddit is, I don’t think Lemmy fundamentally has the capability to be particularly restrictive.
Well, it does say it would be a floating colony, so it would probably be up where the atmosphere is about as dense as Earth’s, and above the sulfuric acid clouds, which is quite a bit more feasible than on the surface. That’s something actual real scientists and engineers have looked at. Still not overly feasible though, and there surely won’t be a 1000-person colony there by 2050. Even if NASA, SpaceX and the rest of the industry pivoted to Venus rather than Mars, I’d doubt that could happen. And I’d trust pretty much anyone more than this guy to pull it off.
