The spam has hit with a vengeance. I'm inclined to agree with a post a while back that it's an actual person, not an automated process. The rate appears to be about 2 per minute, so someone's probably pasting things in. They appear to be from a limited number of users. The username "ha.aaaoruankhueoudstosduerl" looks like the worst, but I don't have a COUNT(*) to use on the web page.
