It would be naive to believe in this "Privacy Pass", which is same as every other privacy joke. Don't take my word, Install this along with uBlock and Chameleon and block all fingerprinting, and captchas won't work, meaning, they don't fingerprint you by how correctly you solve the captcha, but by other methods like how you move your mouse across the screen while trying to solve captcha [https://web.archive.org/web/20180518183337/https://trac.torproject.org/projects/tor/ticket/24321, https://web.archive.org/web/20171122002800/https://trac.torproject.org/projects/tor/ticket/24351, https://www.eff.org/document/crypto-wars]. I've installed "Detect Cloudflare" add-on to boycott all websites that use cloudflare. Cloudflare can take their damn pAsSeS and shove it.
