I don't think anyone cares anymore. Every ad network that slips through is probably propagating whatever data they get across all other ad networks instantly, so they are probably right not to care.

Plus, mine is but a grain of sand in China's endless beaches of data. Also, the only real solution is to use a shady VPN (that is probably owned by a government anyway).

It sucks and is terrible but I think that's just the way it is unfortunately.
