I'm told that if anything offensive turns up, I can ban them. But I haven't fully learned to drive this thing yet, and my readers may not see the same ads that I do. Let me know if there's anything terrible, and I'll do my best to get rid of it.
Edit: This is amazing - I seem to be getting a lot more page views that I expected. I'd avoided counting before because I didn't want to feel intimidated by a large audience or disappointed by a small one. (Yes, I can be hard to please.) And you guys are clicking on the ads! I actually want to click on a couple of them, but I'm not allowed.
So I now feel, like, all responsible. I've added a link to this post to the top of the left column, as "Report a Bad Ad". Anything that looks nefarious - junk weight loss spams, quack miracle cures, mailorder
NOTE: Don't bother reporting it, if it appears on this specific page. Talking about dangerous weightloss spam brings it on like Beetlejuice.
