How cute, seriously, MSN has finally given names to their baby crawlers. You know, Google names their crawlers, i.e. GoogleBot, MediaBot, etc... Yahoo has Slurp, etc. Now MSN has named their crawlers.
The MSN Shopping bot is msnbot-products. The MSN News bot is msnbot-news. The MSN Image Search bot is msnbot-media. The MSN Search bot is still just plain msnbot.
WebmasterWorld moderator reminds MSNdude to update the help pages for Webmasters with this information. This way if you want to block the MSN Image search bot, you can be certain adding msnbot-media to your robots.txt exclusion protocol would work.
