Fake bot from Bulgaria

We see another of those fake bots crawling our sites. It claims to be either Googlebot or msnbot and comes from 212.124.92.58 which belongs to Internet Bulgaria, a Bulgarian ISP.

In its msnbot incarnation, it seems to be particularly interested in our RSS feeds, while its Googlebot incarnation just crawls the site, following every link it can find (and ignoring the robots.txt, of course).

Those running Bad Behavior can relax, as it already blocks these sort of fake bots.
