DDOS-GUARD.NET is covering for scammers. Despite my repeated requests to block the site tdsstat.pw with IP 186.2.168.130, there has been zero response! This site blocks browsers on Android systems (smartphones, tablets), and the scammers extort money for unlocking the browser. I do not recommend honest webmasters use the services of DDOS-GUARD.NET; there is a high likelihood of ending up on antivirus blacklists in the future.
