| You need to try and isolate which of the many Yahoo Slurp bots is using all this bandwidth, as mentioned in the other recent thread the Chinese Yahoo Slurp can probably be blocked without any adverse effect to your site so long as your not marketing to China.
You've said nothing about what your site is or contains, I had a problem with one of mine, where I had forgotten to put limits on a calendar and Google indexed from 1902 until about 2050 before I realised and stopped it. In my case that caused 150 pages of useless calendar data to be Spidered.
Official Route to block spiders is to use the robots.txt, but if this is just a bad bot masquerading as Slurp then this won't help you, in that case you will need to use .htaccess to block the requests.
