Virtue signaling? Preventing completely anonymously accounts doesn't seem to fit that colloquial definition of that, I always assumed it meant taking an action simply for social signalling, that has no benefit to you otherwise.

How about the fact Twitter recently launched an official onion-service yet it is claimed by users when attempting to create an account with email over it the account is locked for 'abuse' within short order?

I certainly understand why you want to use Tor to create a Twitter account, I guess the disconnect is you seem to feel it is fundamentally and obviously wrong to prevent this, but it does seem fairly clear why you'd offer a service to allow logins yet not signups. And in any case, can't speak to why an individual account got banned
