I promise--I'm filtering like crazy, yet the pharmacy ads keep coming!

Look. I am not necessarily anti-Effexor or anti-prescription drugs. I just don't think ads for those things are appropriate for these pages. I've been filtering sites like a madwoman in my Google ad settings, yet new batches keep cropping up--don't want to take Effexor? Take Valium! How about some diazepam? How about a whole crop of drugs with lots of D's and Z's and P's and and T's in the names?

I know ads are automatically served to the site based on its content and the repetition of certain keywords, so if I stopped using some of these words entirely, maybe these types of ads would be replaced by other types of ads. But if I have a huge long list of pharmacy/prescription drug URLs in my list of filtered sites, wouldn't SOMEONE or whatever technology they're using to determine which ads are placed here get the idea that I don't want those types of ads?

I love you, Google, don't get me wrong, and I've been hearing a lot of stuff on the news about you lately about how smart and lucrative you are, but you've just been letting me down. You're still my favorite search engine, but I expect more from you, you know?

Well. I can imagine some readers might be thinking that Effexor withdrawal should be the least of my worries, since addressing entire blog entries to a search engine, which is admittedly an inanimate object of sorts, is clearly symptomatic of far deeper problems...
