why don't add IP range of MSN?

msnbot turning evil
Christof Meerwald reports on his website that:
I created the robots.txt file, I had hoped that msnbot will take action accordingly. But what happened instead is really outragous: the second msnbot requested the robots.txt file, it simply changed its User-Agent header to no longer identify itself as msnbot, but continued requesting exactly the same pages and at the same rate as before.
Maybe it's worth mentioning?
