The best practice is to avoid pages exploiting the users by secretly using their processing performance for monetary gains without disclosing it. However, if you want to continue using the website without being exploited, you can add ||coinhiveproxy.com^ to the filter list of whatever ad-blocking service you are using. At the same time feel free to whitelist The Shotcaller since service of this website partly relies on serving advertisements.
