I think this is part of the catch with all of the concerns here. As a player, where do you look for these quizzes?
If we place them in the TV category for 'Survivor', they become one of the only instances in the category where the questions are not derived from the show.
If we place them anywhere else in the Celebs category, all of a sudden we're separating people who appeared in TV shows out from the dedicated TV subcategory.
The minute we have a quiz that mixes Reality TV contestants, where does that go?
The definition of 'star' and 'personality' aside, the people in these quizzes are from that medium and their success is derived, generally, from TV appearances; it's the thread that binds them. The other catch is that many of the quizzes there were written when 'Survivor' was one of the top shows on TV (twenty years ago!). These people
were icons for an emerging genre of television and many of them did permeate cultural discourse for a good amount of time, often appearing on many other TV shows, in movies, or in the news. This is obviously less so now, especially with 'Survivor', but it's not the line we draw in the sand for disallowing these quizzes.
The likely solution here is to omit the 'Survivor' subcat from TV Stars Mixed in dailies/hourlies. It's a bit disappointing that my quiz-- which I put in there to redress the imbalance of more specific ones in the subcat-- doesn't really help in any way. The problem here is, of course, that doing this cuts out a third of the content (and makes all of those daily/hourly quizzes 20% chefs and talk show hosts).
The solution I prefer is writing for the imbalance, like we ask for in other categories. Yada yada be the change, etc.

It doesn't solve the issue right now, but it seems like people are less willing to help develop a compromise and just want them gone altogether.
Regardless of whether or not people think they're stars, some of us enjoy the content and don't find it embarrassing. But I mean, I guess I'll take that too.
