ELI5: How do TV Street Magicians work? If actors are used then why does nobody expose them online?
gpt
Any magician employing actors to fool people with would get non-disclosure agreements signed by the actors and could pursue civil action (i.e. lawsuits) if they did speak out. So there is little to be gained from actors speaking out since people already know magic acts are trickery, and potentially a lot to lose like the actors job or future job prospects or paying for a lawsuit.
