These scams are real and the scammers are really not letting go of the ideas they've been developing to making sure they get people scammed. Few days ago I received a mail from an unknown source. Although it was filtered and sent to my Junk box where I saw it. A scammer sending a mail trying to blackmail me to sending him Bitcoin and throwing threats that I do not say anything or think of tracking him because if I do the whole world would see my clips. I laughed at him because all that they wrote are just lies upon lies and nothing true about it..
This is a pretty common scam attempt that the scammer made, and it's an old method. If you search on Google about it, you will see a lot of Reddit threads. Basically, the scammers copy and paste the same email to a lot of people saying they have your video clips of jerking while watching porn and something like that. They say that they have been monitoring you for a long time, and they have your private images and videos, but they never provide you with examples of what they have.
This is a pretty old and common scam attempt. People should never send a penny to these scammers. Once you pay a single dollar, they will start asking for more, similar to the ransomware virus scammers. Even if they have your photos or videos, you never know if they will delete it or not.
