Blank pages

My guess would be that these pages are spammer generated, however, what purpose they serve I have no clue about. Once a week or so, I simply go through and delete them, but it's getting quite annoying. According to your suggestion, I have now set the minimum description length to 10 words. We'll see how that works out, thanks for the suggestion. As a side note, the spam-level on the new Drupal-based site is much, much worse than it was on the old site. I get so many bogus acount registrations, its unbelievable: These guys get through the captcha /and/ the e-mail verification. No idea how they do that, really.
