Web Advertising: Peeved by Targeting

In my Yahoo email account, where I basically live and breathe all day long, I am subject to the most annoying ads for wrinkle, cellulite or under-eye circle creams. Obviously, Yahoo knows I'm female and in my 30s and God knows what else about me, hence these targeted ads. But I swear they are going to give me a complex. They all have this annoyingly fake Photoshop thing going on (it's probably bandwidth hogging too) where they morph a wrinkled and embittered-looking woman into a different, happy and smooth-faced woman who is also 20 years younger, the animation cycling back and forth every time I pull up my email. Or they show a woman's butt with and without cellulite. I am so sick of it!

I suppose it could be worse, right? Pharmaceuticals? Things that cause male appendages to grow (I don't need the hits for writing the word)? Something that rhymes with horn and starts with a P? (By the way, I don't know if this is a proven method of not attracting horndogs to my blog.)

Anyway, my point is, having been the trapped rodent in this little Internet experiment for some time now, I see huge flaws with targeted advertising. Someone has paid good money to monopolize my email account and that of others who fit my demographic, but I will never, ever buy their product. Further, the images are upsetting to me. Over the course of months, I have come to hate them with a passion.

How do I opt out of targeted ads? Do I have to buy a proprietary email client?
