Who Is Mining allows you to check whether a website is secretly
The site was originally launched in 2018 as a simple tool to bring awareness on the overly popular "cryptojacking". The activity that many sites started to use to monetise their traffic at their visitors' expense. The cryptojacking represents the activity of placing a script on the website run by all the visitors. Each visitor would then run the script and contribute to the crypto mining activity, eventually generating profits for the owner of the website in question.
The purpose of Who Is Mining is to have a comprehensive crowdsourced, free to access archive of websites that appear to be using cryptominers, abusing visitors' CPU power.
