For events, there should be two warpers, one for restricted (meaning players that have more than x hats can't join) and one for non restricted (anyone can join). That way, people have no room to whine about the competition. The prize for winning the restricted event is just the hat, and the prize for winning non restricted is the hat plus a few hundred gralats, exactly how much depends on the event. If you win and already have the hat, you don't get anything, including gralats. Hide and Seek, Trivia, Chests, and Horse Race work like they do currently.
