Note: I tried to limit myself to continua that actually have PPC missions. There are a few that don't fit this, but I figured that they'd probably be good exceptions.

Making an actual survey on Google or something? That way you wouldn't have to comb through a bunch of Pastebin files to gather data. It would be a LONG survey by necessity, but you could split it up by books, films, video games, etc. to keep it neat. You could use the Fandom categories on the wiki as a place to start for gathering options, though of course not every fandom that's popular now is represented by a page on the wiki and not everything with a page is popular now.

I'd also suggest setting a working definition of "fandom" that fits what you want to learn. Are you interested in every single thing that people might happen to like, or the ones they actively participate in somehow (i.e. cosplay, fan forums, writing fic, making art, etc.), or just the ones they might conceivably write a mission in? Framing the question will get you better, more specific answers, and also make it easier for us to figure out how to respond.

~Neshomeh, who can't be bothered to write out a list of everything she's ever liked but might tick off some boxes for a few minutes.

Check five or ten users, make that your basic list, then leave an open box for 'other'. Put it up on Google Drive or something.

I don't have a user page, but I don't mind listing my favorites here, if that's okay. Or was that what you had in mind in the first place?
