My last project for post share in Facebook: I have 100K collected fingerprints from many web page visitors (device names, screen size, WebRTC and etc. etc.), i can even collect visitor behavior and repeat. I write code (Selenium base) that can masquerade by selected fingerprint according to all possible parameters. The best result is to use ARM platforms (mobile) fingerprints and proxy server (Squid witch 3G/4G dongles for ip rotation). Facebook and Gmail account creation is also automated on this basis. It can now be said that the project is a success.
P.S. However, the codes are getting worse lately, so plan to switch to image processing (based on AI) and stop using it Selenium.
Next project autoclicker by phrase and randomly browse and wait in page (for google, bing and etc.). Now first code demo working - waiting for results. In a future plan to use webmaster data to auto calculate how many times and when make click.
