It's fun to think about what social media your characters would have, you know?
Hayden wouldn't have any for the longest time, but finally would make a blog that's weird aesthetic stuff. Like "dog treat aesthetic" weird. It started more or less as a joke and he just kinda. Had fun with it so he keeps it up and it's all weirdly themed about flames of eternal damnation and milk milkbones and nobody who follows him can figure out what his deal is but it's weird in a fun way.
Red would have a Twitter where she tweets about the latest trouble she got in, and her tumblr would be entirely furry content specifically red pandas. She frequently has pictures of her in situations where she's about to get wrecked captioned with "photos taken seconds before disaster"--she crossposts these to her Instagram which is entirely pictures of her about to or having just been wrecked. One time she had three of her buried under fallen bookshelves in a week and the last one had Blake in it holding a sign over her that said "I like to try to climb shelves I know can't support me because getting a chair or something is too slow and I act surprised every time they fall on me and I need rescuing". It quickly went viral and is her most popular to date. (Blake gets some messages on his blog about it)
Blake would have a mess of a personal blog where he just does something of everything. He has a storm-related sideblog and eventually once his identity gets blown a sideblog specifically addressing heroics he gets involved with and trying to give tips and advice to people to avoid incidents. As things progress he has another he makes and a Twitter he starts specifically for information on demons and avoiding them and plugs his protective charms that he makes for free to help people.
Grizz surprised everybody by having several social media accounts, though nobody was surprised they were dedicated to environmental conservation.
Zu has no idea what this stuff is but learns fast and quickly decides he's gonna run a blog all about the freaky critters of the ocean. It is equal parts informative and utterly terrifying and nobody knows where he gets some of his pictures. (He goes to the ocean floor and takes them himself, being a water spirit and all. The camera just needs a little pressure proofing)
Nobody knows it but Agatha runs two sites, one dedicated to spreading educational references and general ways to better acquire and retain information and one dedicated to birds.
