The most recent RPF I wrote was about a couple of not very well known comedians who did a few episodes of a podcast and said they wanted someone to write RPF about them, so I did! It was short and not wildly explicit, mind you, though unless I’d been unnecessarily cruel about them I don’t think they’d even have minded that (and I couldn’t possibly have been because they’re both lovely and talented). I have to say that isn’t something I ever imagined doing either. And I did show it to them because I wrote it for them, but then they were very pleased with it, so - slightly different, but an amusing anecdote.

Hee, I like that!

And I agree re: public personas of famous people, though I think it can get weird if it's like, Youtubers? People who're connected to a specifically online community. But there are ways to do that right too, I think.
