If you are looking at that page, you were maybe hit by my research/testing bot called autotagger.
The User-Agent should look like this :
Mozilla/5.0 (compatible; autotagger/0.1; http://www.foo.be/cgi-bin/wiki.pl/AutoTagger)
The bot is not a crawler and only target specific page, often found in publicly available url repositories (e.g. dmoz or del.icio.us).
The (main) purpose is to evaluate the possibility to deduce a free classification from the content of a web page. The bot is also serving as an interface to an archiving project part of quuxlabs.
If you have any issue, question. feel free to contact me (the single letter a followed by the domain foo dot be). You can also leave a comment on this wiki page (link at the bottom). Thanks.
AutoTagger bot is able to understand my own MachineTag and some others.
