I have a private wiki that requires an account to view and edit.

I've have several user accounts of individuals that needed temporary access to edit the wiki. Some of these accounts are email confirmed users.

These users no longer need view or edit access however I would like to retain all their edits and have them associated with their accounts.

What is the best way to disable these accounts? And if I ever need to reactivate an account, how would I go about doing it?

You can set $wgBlockDisablesLogin to true. That would allow you to block all accounts that shouldn't be able to log in and if you need to re-activate the account you can just unblock them.
