Please don't do this -- GitHub does not register activity or hobbies outside of GitHub. You are arbitrarily ruling out people on BitBucket, Gitlab, and elsewhere, in addition to the legions of programmers that cannot post their work publicly and do not want to produce stuff on their own, unpaid, time.

Even if you do work on GitHub, when a repo is deleted, your activity on that repo is also deleted.
