There was a follow-up visit a few hours later, with a repeat HEAD request for the specific files that were 404'd earlier. But not the files currently linked from the html page. If I leave the robot unblocked, I will expect to see it some time in 2014 asking for this year's images. (Possibly also the stylesheet. I can't remember if I had one for that specific page in 2012.)
After rereading my post from last year, I went back and looked up my record of the oBot's January 2012 visit. That time it asked for at least one image file in a directory that was definitely roboted-out at the time. :: Hasty edit as I belatedly figure out what it was doing there ::
I've noticed before now that robots may get an unearned reputation for good behavior. Nothing that links directly from my home page is in a roboted-out directory. So if robots go no deeper-- most don't-- there is no opportunity to disobey robots.txt.
