I’ve really enjoyed the videos of James Veitch on annoying scanners. Especially this one: https://www.youtube.com/watch?v=3MHDDSekvcE. The scammer wants him to contact this “bank” and open an account. He than makes up, that he read somewhere that you get a free toaster with any new account. He than goes on and on about the free toaster until the scanner asks him to stop emailing him.
It would would probably kick saurons time table a bit back
