Do you delete all spam MS catches?  If so then I guess you could do the 
same with spam identified by others, but otherwise how would you know 
the score of the spam you received?  Even if you could find it, would 
you trust it?  It could be abused.

I delete all spam which score 20 or more.  This is quite conservative 
but I nonetheless delete close to 90% of all spam MS finds.  That leaves 
10% to my users' scrutiny.  If I elected to trust other sites about spam 
detection I can't think of a way I could still delete all that spam 
without going overboard and deleting borderline spam that happen to be 
ham...

I would definitely not use such a feature!
