Most people at least look up the name of someone they are going to date on social media, or google them to make sure they aren’t an axe murderer, or whatever. Not having a Facebook or whatever isn’t a problem, but the lack of info is. There’s also plenty of stuff that people can let out on social media that you might want to know about, like racist stuff.

A friend of mine dated a compulsive liar. They didn’t have any social media cause it would have made some of their lies obvious. That kind of thing is why some people see the lack of social media as an " orange flag".
