Social media is an extension of your personality.
If you want to show yourself in a different version on social media, totally okay. Just change your character traits and improve your personality. Then start approaching social media again.
If you want to look like an expert investor, be an expert investor.
If you want to look like an experienced programmer, be an experienced programmer.
If you want to look like an artist, be an artist.
But never put yourself in a position where you must work hard to make your personality match the one you imposed on social media.
