The most common high-pressure tactic is the lure of getting in on the ground floor. But in direct sales, a good opportunity is a good opportunity no matter when you get in. In fact, you're safer to go with a company that has been around for more than five years (the longer the better) than a start up. Any effort a representative makes to prevent you from studying the company, talking to others, and "sleeping on it" isn't someone you want to work with.
And these sales aren’t just to customers. You see, in order to join an MLM you usually need to buy products to sell (often referred to as a starter kit, or similar). And then in order to remain a seller, stylist, supervisor, or whatever term the company uses, you often need to make a minimum number of sales in a given time period (though not always).
The Federal Trade Commission issued a decision, In re Amway Corp., in 1979 in which it indicated that multi-level marketing was not illegal per se in the United States. However, Amway was found guilty of price fixing (by effectively requiring "independent" distributors to sell at the same fixed price) and making exaggerated income claims. The FTC advises that multi-level marketing organizations with greater incentives for recruitment than product sales are to be viewed skeptically. The FTC also warns that the practice of getting commissions from recruiting new members is outlawed in most states as "pyramiding".
