Motivation

These days captchas are unfortunately everywhere, with reCAPTCHA having the biggest "market share" in that space (> 80%). The situation got really bad, with privacy minded users (tracking blocker, VPNs) being penalized heavily and having to solve a lot of reCAPTCHA challenges constantly while browsing the web.

These small codes allow us to get automatically google token from 2Captcha Service and bypass google's protection. It is very important for crawler's activites.
