"Not yet verified" would, I think, imply to many people that they will in the natural course of things be verified, and perhaps even that they've asked to be verified.
It would be better to say "Bla is not a user and will not get the money you donate now, and quite possibly not ever", or similar wording. Or just (and this is, er, the obvious approach) not allow this at all for people who haven't asked for it.
