That will very much depend on how you define "social media".
Is italki social media?
Q&A sites like stackoveflow?
LinkedIn (though some people treat that as if it were Facebook)?
If you refer to things like Facebook, Twitter, Instagram,... indefinitely. I deleted my FB account a few years ago, haven't used social media in the stricter sense since Google shut down Google+...
So a "happily ever after" 😉
And as always thanks to my trusty (rusty? crusty? frusty?) downvoting follower(s) =} - you're the reason I can happily do without :D
