Bing seriously hitting our website

[Andy-Halliday]

Hi

I have a strange query, Bing in the last four weeks have been seriously crawling our site, and while at the moment this isn't affecting our servers, coming into the busy time of the year I am just wondering if anyone else is seeing this.

They are basically crawling the entire site (including nofollow  pages) even though according to Bing Webmaster tools, they know our sitemap.

Is anybody else seeing any unusual activity with the Bing bot.

Thanks

Andy

long time ago I saw that on a client website - as german we could block bingbot in robots.txt with no risk to loose traffic.
I don't know why but the server was highly stressed by bing bot. 
So yes I saw something like that - a little bit more than a year ago - but I wasn't interested in the "why?" - I just blocked the bot.
