Not linking your social media with your real name, for starters.

If you want to start a brand/identity with your username that reflects you, that's great, but understand that that comes with every part of you. It's clear you understand that, and that you don't want certain aspects to be exposed in fear it will ruin your reputation.

So the best suggestion is having a different username, one that is different from any that ties you to your personal life.

Take me for instance. This username I made up on a whim. I'm not 42 years old, I wasn't born in 42, the number bears absolutely no significance to me. In that, I have confidence to share exactly what I feel and not worry about what anyone else thinks or people tracing this back to who I am.
