This is the main inescapable one for me. I have uMatrix to block analytics and all that, but so many websites simply wont work without recaptcha.

My solution lately has been to feed them junk data until they either give up on me or erroneously perceive my input as non-erroneous (not sure which it is). Takes some time, but to me it’s worth it. If we can get enough people doing this they might have to get rid of it all together. (Vastly unlikely, but a guy can dream, right?)
