Fraud and Scam are not synonymous. It's quite possible to take advantage of people in dishonest ways that are not illegal or fraudulent. Look up "Don Lapre" if you don't believe me. Has made a long career out of doing things that are quite clearly money making scams, but has never even been accused of a crime. Lotteries and casinos are basically legitimised scams that prey on people who don't understand probability. And 'contests' which use the common psychological tricks to convince people to hand over free work for no pay and little benefit are also scams.
