aggressive bot (multiple requests per second)
2007.05.07: seems to be a malicious browser-extension that explicitly requests disallowed pages (via robots.txt) that are linked by user-visited page to harvest e-mail-addresses and guestbook-forms.
2005.09.20: came from, querystring correct
2005.09.11: came from, converted querystring to lowercase
