When I went travelling some years ago I created a Instagram for my family and friends to get a peek of what I am doing.

I did mediocre pics with kinda personal content but soon more and more followers showed up, likes increased and nice comments appeared. Not much later I would get offers for advertisment deals in my DMs and weird people offering to show me around.

I didn't care, but I totally see why a more fragile, or narcissistic for that matter, personality may gets sucked into this.
