David Thomas Baker » Web » search.live.com/results.aspx referral spamming

im getting lots of these across a whole bunch of apache log files:

Referrer: http://search.live.com/results.aspx?q=keyword&mrt=en-us&FORM=LIVSOP
IP Address: 65.55.165.88
User Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.2; .NET CLR 1.1.4322)

After some googling it seems this is part of some live.com's search engine quality checking blah blah

I have heard the bot downloads javascript and css files as well... who knows what this could be doing to things like adwords or google analytics.

So I just blocked them:

if(preg_match('/^65.55.165/',$_SERVER['REMOTE_ADDR'])){
        header("Location: http://microsoft.com");
        exit;
}
