thanks for checking it out and for the feedback! I had the same thought regarding just giving spam another target!. My quick thought on a solution... the referrer matters a lot. If we can get this to catch on enough that the problem emerges, we'll have the referrer confirm the referral via email. If there's spam with a bunch of different referrers, we can use some simple classification techniques to look for junk senders and require whitelisting before they can flood the system.
