Notou que um public_html obteve uma permissão 4750, em vez do clássico 0750. Eu tento mudar o proprietário, ou as permissões, mas o que eu faço, ele permanece 4750. Alguém tem uma idéia de como alterar a permissão em uma pasta que ficou presa no 4750?!

Você deve ser capaz de limpar o bit setuid com
chmod u-s public_html
Em man chmod :
chmod preserves a directory's set-user-ID and set-group-ID bits unless you explicitly specify otherwise. You can set or clear the bits with symbolic modes like u+s and g-s, and you can set (but not clear) the bits with a numeric mode.
