I have refused to use dozens of service which required me to click pictures to prove that "I am not a robot" and sent the service provider an email informing them of my decision. I would urge everyone to do the same.

It's amazing how much you need to break free from tracking, but I'm on the war path :) Btw, taking the red pill will cut you off Facebook and Google accounts, unless you provide real phone numbers.
Matrix movie: "You take the blue pill – the story ends, you wake up in your bed and believe whatever you want to believe. You take the red pill – you stay in Wonderland, and I show you how deep the rabbit hole goes"
I've started noticing that if you're sneaky you can get a surprisingly large tolerance for error. I've no idea how effective that actually is at poisoning results.
There is an (admittedly a little nasty) part of my brain that really likes the idea that if I'm being asked to provide free labor for a proprietary company, then I'm not really under any obligation to be a great worker.
Just refusing to use the service is probably more effective though.
