The only business that relies on tricking people is magicians. Anybody else, and we call them crooks, and put them in jail.
Except the guys who manage to toe a fine line between warning you not to be stupid, and make you fall for the scam any way.
Here's one example... In California, every corporation incorporated here have to file an annual "minutes" with $25 processing fee that basically updates the government on how your corporation is doing, and who are responsible. Here is one such form:
However, there are some "legal scammers" out there that want to do the same work, except charge you $75 more, for a total of $100. But you do all the work any way, since you get to fill out THEIR version of the form, all the same info. They just copy your info onto a real form, and pocket the extra $75 you sent in. Sounds like easy work, doesn't it? Here's such a form:
He's making money even if he got a response of just 1% (i.e. only 1 out of 100 fall for this "legal scam"). Yikes, too bad real businesses don't profit like that.
