The Informant is a bot that will crawl listings of the search engines and report when there are any sites that appear. It is a university's CS project. informant.dartmouth.edu [informant.dartmouth.edu]
"The Informant is a FREE! service that will save your favorite search engine queries and web sites, check them periodically, and send you email whenever there are new or updated web pages."
Here I thought I was the only one that knew about the Informant. I find it is a killer tool. I use it all the time and have toyed with a similar rank tracking system for myself. I've thought about putting it on sew, but I got enough se raiders and emailers going on now. New domain time for some of these tools...
Only problem I have with Informant's spider is that it is not identifing itself, in fact I've 403 it on server level because it started getting very aggresive.
Anybody familiar with griffon/1.0 (firstname.lastname@example.org)? Its been knocking on my door for quite some time and I decided to let it in as it seems to resolve to some sort of japanese SE/directory, so far its behaving itself but I did not see any surfer visits from navi.ocn.ne.jp in the logs yet.
