Today i got hits from MSRBOT of microsoft and getting 404's. My log excerpts,
131.107.151.zzz - "GET /not-there-1.txt HTTP/1.0" 404 42 "-" "MSRBOT (http://research.microsoft.com/research/sv/msrbot/"
131.107.151.zzz - "GET /not-there-2.txt HTTP/1.0" 404 42 "-" "MSRBOT (http://research.microsoft.com/research/sv/msrbot/"
The last number in the ip range is 3 digit, don't know, why 3 x's change to these things! There is some strange thing in its behaviour,
a) it is asking for non-existent page
b) When i tried to view the URL it supplied in UA string, i can't reach anywhere. After google-ing i found one page here.
This entry is from that page
| Why is MSRBot trying to download incorrect links from my server? Or from a server that doesn't exist? Because MSRBot obtains the list of links to crawl by extracting them from documents on the web, there must be an incorrect link available on the web. To determine the location of this links, look at the referral field in your web server log. |

Now, how i am suppose to look for the referer, if it is blank, is anybody's guess. ;)
i found this post in WebmasterWorld.
Note, before they were crawling from above.net, ip - 209.249.11.x and now they are coming from ip owned by microsoft.
Since their behaviour is suspicious i banned them through .htaccess.
anybody else seeing this?

There's hordes of this IP in the archives.
They betting eating 403's from my sites steadily for weeks. There's a recent thread where Brett advised that the range was utiized by MSN's research team. Here's somethings very old:

Thanks Don, Not only those two posts, i have visited some others from there. So they were doing this from 2003? and nobody care to answer anything from microsoft.
Well, at least in my case, i am going to ban the full 131.107 range.

... at least that MSRBOT seems to obey the robots.txt. Just seen one lonely "GET /robots.txt HTTP/1.0" of MSRBOT in last week's logs. As that bot was disallowed /, it apparently moved on and left my sites alone.
