MoveVandalism
The best way to fix vandalism that includes a move is to move the page back first, over the redirect, then to revert to a good version in the history.
If a System Administrator deletes the bad page instead while re-creating the good page by copy/pasting from the bad page history, it gets a bit more complicated. Here are the steps (please update if needed):
- delete the correctly named article
- restore the incorrectly named article that was deleted (this one has the bulk of the history)
- move the incorrectly named article to the correct name
- delete the newly-correctly named article again
- restore the correctly named article (this brings in both histories)
- the last step is one I forgot, which is to delete the incorrectly named redirect that's left over - not sure if this matters
Maybe an example here would help?
Let's say the page vandalized is called ReallyGoodPage. It's edited to include a nasty image and then moved to ReallyNastyPage.
The good way to fix this is to move ReallyNastyPage to ReallyGoodPage over the redirect, then delete ReallyNastyPage and restore ReallyGoodPage to a previous version that's good.
Sometimes a System Administrator will simply pull a good version of ReallyGoodPage from the history of what's now ReallyNastyPage and copy/paste that to be the current version of ReallyGoodPage while deleting ReallyNastyPage which contains all of the history of ReallyGoodPage. That's when the numbered steps above are needed.
