I previously tightened the comment system to prevent the zipcode troll to spam comments on this site. Now, I've taken care of the troll who insists on selling me various things to improve the size and operation of one part of my body which quite frankly doesn't need anything of that sort, thank you very much.
Feature request to weblogs developers: I'd love a comment system that is less prone to spamming. I have no secret recipe though. And I know that if you make it more spam-fool, nature will grow a better spammer, but that's not a reason for not doing anything.
