Usually the most reliable data-gather are actually the ISP, which are not obligated under US laws to hand them out easily.
There are actual cases of some third party investigators inflating the data to suit companies needs to lobby claims against pvp trackers.
If your ISP is gathering data on what you are actually downloading (versus just the protocol you're using) then I would seriously consider finding another ISP. Any ISP that is inspecting packets vs just gathering protocol metrics is in serious breach of my trust.
