You're hoping against both human nature and statistics. Even if 99% of people are decent, that 1% will still eventually screw you over for their own profit.

Maybe it will come to active countermeasures. For example, you could set your browser (fingerprint and all) to trawl through an invented web history to poison tracking databases. Running such a program would both screw with the trackers and give you plausible deniability. Tag other people's selfies with your name on "social" sites, and tag your own with several names.
