I was going to start doing this myself, but I figured it'd be better if people talked about it first, and more effective if they knew about it. Instead of blanking articles why not replace the article text with a redirect to a boilerplate text with something along the lines of "The content of this article is being disputed. It has been blanked for the time being, though older version are still accessible through the Page History. It may have been blanked because of blatantly false information, or non-encyclopedic garbage. This article may be awaiting [[votes for deletion]], or awaiting a sysop to delete it. Please use the Talk Page to discuss this dispute if necessary, and check [[Votes for Deletion]]" I wouldn't recommend that exact text be used, but basically, my idea is to redirect articles to a boilerplate text explaining what's going on rather than just blanking them. That way, Googlers and people who located the article in the index or search function will know what's going on.
