This has been done in the past, it didn't go well. Advertising networks eventually kicked the person off their networks because 'anonymous clicks' weren't valuable to them. If they don't tie your identity and your click traffic together, the data isn't worth anything to them. http://www.torfox.org/ used to be a custom Tor browser that integrated torbutton into the firefox codebase. See http://web.archive.org/web/20090628072441/http://torfox.org/ for that history. It also included a configuration that forced you through the torfox exit relays, which conveniently used javascript to automatically click on ads that you the human never saw. The torfox exit relays were unpublished relays and hardcoded into the torfox browser. In a conversation with mister torfox himself via a .onion forum, he claimed to be making $350,000 a year this way. It was later revealed the $350,000 was the sum of all their ad network hacking, not just torfox. And it all went away when the ad networks disabled his accounts for click fraud. -- Andrew pgp key: 0x74ED336B _______________________________________________ tor-talk mailing list tor-talk@lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-talk
