Containing the '?action=edit&' I have changed this in my local copy of the wiki to be:-
I have seen a reduction in WikiSpam. As many bots are trying
$ActionEdit = "edit";
It would then make it easy for users to change this option and very hard for bots to automate editing.

"very hard for bots to automate editing" - not at all. They just do a regexp on a normal page.
