Spam clicking on ads won't work, and at worst you'll actually cause more damage than good. Any ad provider worth anything can and will monitor how you're actually interacting with their ads, and creating a bunch of fake clicks may get you and the source flagged.
I don't know if it's still happening, but there are stories about google adsense deleting accounts and refusing to pay out because they detected bot-like activity that some completely unknown 3rd party had caused. It might be that you can still fuck over people's ad money by botting their ads, the providers won't care.
