I believe the time and resources required for us to develop such a tool and the time invested of users to run it is much more than the total inconvenience it would cause to surveillence systems.

But please prove me wrong, Id love to run such a tool quite easily, even if it doesnt work, just for shits and giggles and just perhaps for that extra cent of cost and resources wasted of powerful organizations. (still kind of our taxpayer cents but...)

Would you run a simple browser extension that would GET pages while you are away, pages that your browser has seen in your history, and an advanced mode, pages on pastebin and a selection of forums/sources? Meh, could be done with a simple bash script and curl I guess for the advanced users. Would be nice if it could also crawl most news sources.

Stepping the idea up a bit, random but seemingly valid User-Agents, exchange of tracking cookies with other users of the extension, and click on all the ads! Would you use such a tool?
