How do you reconcile the idea of keeping your digital footprint that can be tied to your real life personal info minimal in order to reduce your chances for getting hacked in some way, and marketing yourself with resume websites/portfolios/linkdin/public gethub accounts/etc. ?

As someone who is just gotten to the point of starting some freelance work and applying for jobs, not sure how to proceed.

For example, I want to upload my resume website I've created to my webhost and submit it to r/design_critiques, but then I will be exposing my reddit account to my real name and info. How do I reconcile that?
