anyone know who this site is. is it part of msn?
 

i was looking at my referrer logs and one of my top referrest is http://cc.msnscache.com/cache.aspx who the hell is that? then the referrer right below that is http://cc.msnscache.com/cache.aspx?q...-US&FORM=CVRE5 and it does show my site. is this msncache part of msn or is it something that is suckin up my BW

Never seen it in any of my logs before.

Running a whois on msncache.com should tell you who it is. Its definately not owned by microsoft. Looks like its someone from Bulgaria..

should i try to block them?

this just means that the surfer is looking at the cached version of your site.
and yes, it is msn owned
see the link in the search results that says cached page
http://search.msn.com/results.aspx?q...F+&FORM=Q BRE

& no, it's hosted on their bandwidth, but the surfer probably clicked the link to your site & that's why it shows up in your refer log
