Fake msnbot

hit my bot trap, got banned

[Hetta]

It tried to pick up a thousand or so of my pages, but it got banned after a few dozen.

Here's the IP and UA (a line from my log):

63.223.69.#*$! - - [06/Feb/2006:15:07:55 -0800] "GET /page.html HTTP/1.1" 200 4080 "-" "msnbot/1.0 (+http://search.msn.com/msnbot.htm)"

That IP block is "Beyond The Network America, Inc.", should I block it?

Thanks.

[Pfui]

I did. They hit me yesterday morning. From the same IP, running the same (apparently) spoofed msnbot. Ignored all rules. Grrrr...

Does Microsoft sell/license their bot to others?
