Yeah, it was that experience, plus a few of my own, that prompted me to say it how I did, at a simple level the most accessible website in the world is utterly pointless if it's blocked by all the search engines and email providers because it's a spam haven. I'm not in any way opposed to this idea, haven't thought it through enough, but I am opposed to the line of thinking that says fighting spam is a lower priority than X, Y or Z-anything short of the site falling over or stopping working is lower priority in my mind, but of course other factors need to be taken into account when lookign at the bigger picture.
