Proud Member of Project Honeypot
Since I've just gone to all the trouble of upgrading to MT 3.17 due to annoying trackback spammers, it's appropriate that the upgrade now allows me to join a network of folks running Project Honeypot. An enterprising organization, they've come up with a tool to collect data on spammers and data harvesters who then generate a lot of the spam we've all grown to hate.
It's pretty simple: hidden on this page is a link that won't annoy you, but is likely to get picked up by a "non-human visitor." If the link is indexed and searched, and the resulting email address used, information on this is kept by Project Honeypot. Whenever they can, they then hand this information on to authorities for prosecution and (presumably) lawsuits. The legal muscle for this seems to be provided by the Internet Law Group.
Anyway, it won't have any effect on the site directly, but it's my little effort to help someone else hunt down the bad guys. If you're on MT 3.0 (or any of the other utilities supported by the Project), I'd strongly recommend setting one up. It's easy, it doesn't seem to increase server load at all, and who knows: it just might work.
