MSNBot has had many issues over the years. Many times MS folks denied them all until someone actually caused a big fuss. Once it was me causing the fuss.<p>When you think about it, bing/live/whatever it's called today sends very little traffic, and the crawler to get that traffic has a long history of what you call bugs. The cost-benefit analysis IMHO points to too much cost for really zero benefit.<p>Hence why many webmasters block MSNBot.
