Send message as an image (so I cannot copy) demanding payment in bitcoin to this account/address to prevent release of porn videos that victim was allegedly watching.

What the others said

This account was recently been hacked. Im hacker who exploited your email and devices and gadgets two months ago. Clearly, I believe, 1000 USD will be a realistic amount of money for this little riddle. I have managed to create dual-screen movie. The 1 screen reveals the film you had been watching, the 2nd part reveals the recording from your webcam.

The usual I have hacked your system and have a video of you whacking off to porn and will show your family bollocks. Wants $1000. (To not release data he/she doesnt have.)
