First of all getting socially proofed does not necessarily need you need to get to the club with hot girls. Only having a friendly conversation with a hot girl gets you socially proofed, check out my main wing and bro Alec Rolstads series about social proof and how to get it.
Secondly i would not close down low value social media as Facebook or Twitter, having high status social media platforms can increase your attractiveness. The thing I advised was that if you don’t have any high-value social media don’t share it with these girls. (There’s ways to make instagram accounts locked from prying, also Facebook has this setting.)
