How to scrape Perimeter X: Please verify you are human?

When scraping pages protected by PerimeterX we might encounter messages like "Please verify you are Human: Press & Hold":

This message means the web scraper has been identified and is being blocked. PerimeterX is using various fingerprinting and detection techniques, like:

• Javascript Fingerprinting
• TLS fingerprinting

And other details like request pattern, HTTP version etc. To avoid being blocked one option is to fortify the web scraper against these identification methods.
