Just tried it out with the manual block page at < http://www.google.com/reviews/t >

I notice that when I block a subdomain (eg, http://answers.yahoo.com/ ) the page actually shows the entire domain (yahoo.com) as blocked.

Is this just an error in the display, or does it actually only block based on domain? If the second, this significantly limits the usability, since I can't block < http://someobviouslinkspam.blogspot.com > without also blocking every blogspot.com site.
