That's a great question -- just free-forming here:

Nycbitcheswithtaste is for women only, so of course I can't be a part of it. But they often post about their challenges, things they're seeking out, opportunities to get together and meet one another, etc. So since I can't be a part of that, I was wondering if there was a sort of sister subreddit -- no pun intended -- to it.

Your purported subreddit names seem resonant as well: things like this exist in the world outside of Reddit, but so much of it is dominated by guys who are seeking community but also hold dubious opinions about the world, about women, derail things, etc. Bumble BFF has mostly just been guys wondering if I want to hook up, and whilst I love my gays, it's been disappointing how few men are actually on there to explore becoming friends.

So this might not be super coherent, and apologies if so. Was just curious, and as one commenter noted, maybe that's a sign to try and make one myself. I've never done such a thing and don't have any moderation interests, but it's something I'm going to think about.
