Alot of idiots go tout after a rush of positive variance. Usually they are life long losing gamblers. They go on an inevitable hot streak, which is "documented" on one of their numerous forum accounts, then market themselves as the next big capper wth unique or superior handicapping methodology.

People will give these self promoting nobodies money for coinflip picks and analysis all day long, hoping they have found the next big capper or just for the extra risk associated and the hope that all of their paying worthless cappers has finally led them to their winner.

Most long term winning gamblers make enough money gambling. They also realize the long slow grind of making money is not as glamorous or fast as alot of salesmen/touts portray, thus making it harder to compete with touts without resorting to cheesey and misleading salesmanship. The added frusteration of dealing with gamblers, most of whom will lose long term even if they have 57-58% picks, also discourages winning gamblers from selling picks.
