Ha ha no, anonymous message boards are different. They even have a different name. Instead of social media, they're usually called message boards or forums.

When people say social media, they mean Truth Social, Twitter, Facebook, Instagram, Snapchat, Tik Tok, Youtube, Pinterest, etc., etc. I've never had a social media account and never will. (BTW plenty of forum members have expressed that exact same sentiment right here on GAW.)

That said, people are free to call message boards social media if they like. Freedom of speech FTW
