Speaking as an admin who has had serious spam issues with our wiki (we had a situation where a single user went through the wiki and deleted the text off of every page we had), we just lock down individual pages as spam happens so only registered users can edit, and we delete spam pages and admin protect them to keep them from being recreated.

Unless the page is under heavy spam problems, it would be wise not to admin lock pages. It cuts down on users who would traffic your wiki since they cannot otherwise interact with it. The registered users protection typically only allows users whom have been on the wiki for a short period AND have an account to do any editing.
