It is the same with card counting. If you go outside of Las Vegas into "normal America" and mention something about card counting to 10 people, 9 will say something about it being illegal, when it isn't illegal anywhere in the country. Casinos and the original Griffin databases did this by intentionally lumping cheats and card counters together. It took Grosjean's lawsuit to get them to stop.
I went back to Florida for a high school reunion about a decade ago. I hadn't kept in touch with anyone and no one knew what I was doing for a living or where I was living. When I told a few people that asked, every freaking one of them said something about that being illegal. Eventually I started just saying in business for myself, but that doesn't really work either for most of them.
