So?

They can require these things all they want, the correct reply is N/A or / - meaning “I don’t have an Instagram or a Tiktok account” (and if you do have accounts, it’s not a crime to pretend you don’t).

And that should be the correct reply for a decent employer to rate the candidate above those who stupidly provide the information.

Conversely, if the employer thinks not having social media accounts is a minus, it’s probably not an employer you want to work with anyway.
