Nothing much, on our end. It does keep the bots from achieving their goal, though.
While annoying, the whole "creating page with lots of links" thing isn't for our benefit. Is is, essentially, a google bomb. It's done to present google's spider (and those of other search engines) with extra links to the page in question in order to improve their placement in search results, and as such, if the page is blanked before a search engine's spider sees the page, the bot has failed. Otherwise, it has succeeded, even if we later delete the page.
So really, it's just the part of me that doesn't want malicious bots achieving their goal that suggests blanking it. It makes little difference for members of HLP.
