I don’t think that glamour has to be lewd for people to pursue it. As long as it’s cool-looking or looks nice on my character, I’ll do what I can to try and earn a piece of glamour.

My only concern for rewards strictly for the top of the leaderboards is that most will likely go to crafting/gathering bots that automate this entire process. Legitimate crafters will likely be very few. But this is a concern with the leaderboard in general—even if there weren’t rewards attached, I’d expect to mostly see players that frequently bot crafting on there as opposed to legitimate crafters who craft manually all day because they enjoy it.
