People register all kinds of names and if you see "nonsense" domains at "unsellable" prices, rest assured those are not registered by pro domainers. And no, nobody has access to domains at 50c a piece (.com), best you can find is slightly below verisign's price, like $7.99 at some registrars. "Domainers related to registry/registrars" will actually have worse prices because usually they won't be able to use promotions (for various legal reasons), but they can register/renew at-cost (which for .com is around $10).
