That's assuming they can dis-aggregate my traffic at the F5 gateway well enough[0], otherwise they're just saying all traffic out of that rack in Dallas, TX is invalid. A personal web browser clicking ads on pages i visit doesn't feel very fraudulent.

[0] google routinely can't, and i stopped using search because it made me do photo captchas every time. If google can't, i'm guessing other people are going to have less luck.

Being Captcha'd likey means that those systems know not to trust your clicks. I seriously doubt you're doing any damage here, and at worst you're helping the companies you dislike.
