Subreddits dedicated to LARP (not the actual LARP)

I love subreddits where people LARP as social media users from other universes.

Earth25, dedicated to DC universe.

Earth199999, dedicated to Marvel universe.

DCAllies, dedicated to alternative universes where different franchises (mainly superhero themed ones) swap places in terms of media. What if Netease made a hero shooter based on Image Comics. What if Kevin Feige made DCU and Snyder did the Boys, then later was replaced with Gunn
