Recently MSN bot keeps crawling my site almost all day long and sends the loading to the roof. It is really a DOS attack. I googled it and found many people have the same problem. How can I stop this from happening? Using robots.txt? I also heard the MSN bot does not follow robots.txt and heaves really bad.
BTW, whenever i see the word bing, I want to vomit.
Did you determine it was MSNbot by the User Agent or IP?
I've been seeing the same thing lately and it's most certainly MSNbot and Bingbot from both IP addresses (do they really need so many?) and the UA. The also send a no-cache header which really messes up my squid front end.
