You are welcome to hold onto your belief that downvoting posts by new users is unfriendly, or unkind, or "disgusting" (as jasmine stated, I believe), but there is
nothing that you can do to stop it. Not as a user, not as a moderator. The
only people who could potentially change this are SE staff. I would invite you to post a feature request on the main
Meta, and see if you make progress.
