I have developed a piece of software, that lets you auto mass call scammers! You just have to enter the credentials of any FireRTC account(which is just used by you) and the scammers number and press start. The program needs the credentials, because you are automatically logged out from FireRTC if you close chrome.
4.5 .NET Framework
Google Chrome as your default browser (settings/default-apps)
Have fun :wink:
