A probably incomplete list of actions MCU heroes would do on social media:
-Pre no way home Peter Parker has an Avengers YouTube Account, but no citizen knows who runs it. He posts videos with the Avengers like cooking videos or them reacting to Tweets.Maybe he has a Tiktok Account as Spider-Man, where he explains science to his followers in his costume.
-Wanda and Vision have a couple Instagram Account. It has a beautiful and simple aesthetic with perfect pictures of them. You can see them going on a hike or laughing together. There are also pictures with their kids. Strangely, they haven’t posted anything in a few months.
-MJ has Tumblr without a doubt. She posts her sick drawings there. She also uses Pinterest for inspiration. She has Instagram and Tiktok but isn’t active.
-Tony Stark has Twitter. He makes sarcastic and controversial Tweets. Either you love him or you hate him. He says what he thinks and that doesn’t always have to be right. He receives a lot of hate. He also has fanart as his profile picture and changes it regularly.
-Natasha Romanoff surprisingly uses social media a lot when there are no missions and she doesn’t have to hide from the government. She shows how she trains and explains a few simple self-defense techniques. She’s obviously a feminist. She fights against the bad guys and against everyday sexism. She also has fanart as her profile picture and her community is amazing for the most part.
-Bruce Banner helped Peter with a few of his Spider-Man science videos. His videos are very popular. He also did a few YouTube Videos, where he explains simple science and everyone thinks he is good at explaining. His account is called “Bruce science corner”. He also posts science facts on Twitter and reposts fanarts. On Instagram he sometimes posts weird Selfies with really bad lighting.
-Shuri is a Meme Lord. She had Vine and has Reddit and Discord. She makes the best science memes. No one knows her true identity there. On Instagram, however, she shows her more official and royal side. Sometimes her nerd side shows itself and she posts videos from the laboratory in her story.
She knows Peter Parker from a Discord server and they are internet friends. She’s also becoming friends with MJ. Somehow they have the same sense of humor.
-Shang-Chi has an Insta fanaccount along with Katy for some of the avengers. They made it while they were drunk. Somehow they managed to get a few thousand followers through a few posts and it would be a shame to delete the account. On his private account he posts pictures with Katy and Wong at the karaoke. He loves Memes and always sends them to Katy.
-Wong is a swiftie and he was so proud, when she followed him back on his insta. He doesn’t post often, but when he does, its either videos of him partying or videos about topics that are close to his heart.
-Steve Rogers tries at least.
