My logs show I'm still being hammered by these 'fake' searches, even though they've been eating 403s for almost a month.

The good news though is that despite banning the nuisance IP range, we've seen an upturn (up from 1% to 3% of total) in the number of genuine searches coming from Live Search and the real bot is happily spidering away and updating cached pages.
