How to setup FireRTC for scambaiting:
After you have made a FireRTC account change your number because scammers usually block numbers that look like FireRTC numbers. To change it, look at the top right corner of the website click the 3 lines and click settings. Then look at your caller id click the text box then change it to something legit (make it look like a real number) then click save. It will ask you to reset the phone, to do that you go back to the main page of firertc (your other firertc tab since firertc settings opens a new tab) then reload it and done
If a scammer blocks your fake number, just change it again like you just did.
