Sometimes I want to write an ad blocker that actually goes on the offence. Every time it blocks an ad, it should download a few hundred megs of ads from the offending server and drop them in the ethernal bitbucket in the sky. It would either cost them money or get me banned from seeing ads, both are fine by me. Then drop it in an app store, get a few thousand users, and see them squirm. I'd call it Do Not Track, with a mind diseasing number of exclamation marks after it.
Alas, this would probably violate some real laws, plus messing with shady businesses might make them search out other than legal means for getting redress. At the very least, Baron Google would banish me from their land.
Oh well, a man can dream.
