Consider this user: https://mathematica.stackexchange.com/users/296/tatsu

He or she asked a suite of pretty bad questions, only one of which (I think) has been retained, presumably on the grounds that the grounds that my answer to it was worth keeping.

But I have recently read on meta.SO that unregistered users can only answer, not ask. Is this true? If so, why is that not true on Mathematica.SE?

Fortunately we have not had any other cases of bad questions from unregistered users.
