Forum:User made pages unavailabe by redirecting links

Hi I'm adminisriaror of the http://kubera.wikia.com/wiki/Kubera_Wiki, a use made hunreds of edits some good but made data that i used every day inexcessable. By redirecting page, so data was put there by the creator of the wiki and is unreproducable. i block the user for 24 hours after he came back he did the same things so i reblocked him .So he went off to two other wikis i created, being much smaller he could do little harm. I just edited out untrue remarks on his user page

Is therre any way to reterive the lost data from the http://kubera.wikia.com/wiki/Kubera_Wiki.

Thanks Mark
