So tonight I had an idea, I decided to make a fake BSOD for my VM. I am not great with coding or anything like that by any means, but I found some code online that I could save as a .bat file and run it, and it looked just like a BSOD (Windows 7 and down BSODs that is). I made some changes, instead of the usual BSOD message of “your computer has encountered a problem and needs to be shut down” and on, I changed it to make the scammer mad, as shown below. It takes up your full screen, even though it looks like it in the picture.
Also, here's a link to a video of it too:
