This really ticked me off when I saw it. :o Luckily the power went off for an hour so I could chill.
Anyway, I think this might be some one running their own personal bot but I'm not sure. They entered the site by following a link from an se. Then they made 876 requests, 843 of which were for pages in 42 minutes. They did not request robots.txt The site itself only has about 120 pages so they requested the same files many, many times.
If anyone has any info on this I'd really appreciate it. :)
