Not that I'm aware of, I might be wrong. However, it was basically the first one to do this sort of thing...right. Therefore, the name "preev" is somewhat like a brand name, similar to how IKEA doesn't really have anything to do with the stuff they sell, but practically everyone knows who they are, and what they do.

Since it was in the game early, and was reliable it has built up that reputation. I imagine the owner does know the worth of the domain, and if they don't have any interest in continuing the site, will probably look to sell at some point. It's easy to forget about a sites hosting if it isn't costing you much, and you aren't adding any additional functionality to the website. Obviously, not the best practice, but I know its done quite a lot, even massive companies have fallen into this trap.
