Well, assuming that they have multiple administrators, one of the other administrators could remove the original creator as an administrator and block them from hijacking the page. The creator isn't necessarily the owner. I could be wrong, but I believe that if I created a page and assigned you as a co-administrator, you could turn around and remove me as an admin, thus transferring control completely away from me.
