Someone from rteldencus@outlook.com sent me this message: _x000D_ I recorded your webcam which shows your greasy sexual actions & video you played on the xxx videos because that website was infected with my malware. You are appearing appealing in the video recording. The malware also sent me each and every of your FB & email contacts plus the recording. _x000D_ Ill email your video to your friends unless you send me $4000 via Bit coin within the next 24 hours to the below address: _x000D_ B I T C O I N Address: 1PB9KAn4aegC1q477A7gFpyNH3HVG5haDD _x000D_ Make sure to Copy and Paste address because it is CasE SenSiTiVe. _x000D_ Once I get the money, I will destroy your recording and every bit of information I have about you.
