Disable Site Delete plugin only allows network administrators to delete a blog/site on a WordPress Multisite network. It does not allow blog owners to delete their blogs.
It works by doing that in 3 steps:-
<ul>
<li>Removes the delete Site link from tools menu for non network admins</li>
<li>Breaks out of wpmu_delete_blog function to avoid deletion of blog</li>
<li>hacks around option to avoid sending the delete confirmation mail to blog owner</li>
</ul>
