I am currently trying to purge the Beatles Wiki of all the dead wood that is clogging it. I think I've managed to remove all the conspiracist nonsense which treated the "Paul is dead" hoax as if it weren't a hoax, but I have stalled at the next stage, to delete all the unused redirects. I have tried going to Special:BrokenRedirects, copying the contents, pasting them into Notepad++ to convert them into plain text and from there into MS Word for some regex editing to trim the list to just the page names, then pasting the final list into Batch Delete; but although Batch Delete worked before (to purge all the blank placeholder pages, which fortunately were categorised as such), this time it just gave the error "badtoken" for each page!

I don't know what is going wrong here. Surely there must be some way of bulk-purging unused redirects?
