I thought my site was safe from spam because it is relatively obscure, but it turns out not. I was recently alerted that 120 comments had been posted to my blog. This is an unusual feat because there are only about 7 people that visit this site, 5 of which share a substantial portion of my DNA, and none of which generally have much to add to my ramblings. Alas, automated spam bots visited my blog in the night and posted helpful comments to all my entries like "Get CHEAP Paxil & CIALIS NOW!!!" and "Do YOU want MORE SIZE??!?"
The short of this story is that comments are no longer enabled. No real loss, save the increased frustration I have for spam.
