I once served a mostly-unmaintained world-writable wiki. It was getting hosed by automated link spam. Simply renaming the "edit" url to "ed1t", solved the problem for several years. It forced a human to eyeball the site, and thus to notice its high-profile warning that "robots.txt blocks indexing, so link spamming won't be of any use to you". Eventually someone started spamming anyway... which eventually obscured the warning... and the site was then trashed. Sometimes even a very small work function can be quite useful.
