It seems that the URLs I had Google remove using Webmaster tools resurfaced on March 4. I have since blocked them by robots.txt just to make sure. I didn't block the robots before because some of the pages 301 to others, so I thought I might as well keep it crawlable but not indexed (the pages were moved to a subdomain). So instead, now they just can't be reached at all by directory.
