I dislike the idea of adding even more rating levels (diamond, etc.); that just adds to confusion.
Also, I am dismayed that some people think cracks are OK. They're illegal, last time I checked, and I don't think winehq should advocate their use.
How about this: I hear that Alexandre is going to be working on implementing copy protection soon. Once he has that implemented for at least one popular application, how about we revisit the appdb ratings question?
