If the MLM says your revenue will explode with almost no effort

As mentioned previously, not all companies marketing their products through MLM style systems are scams.

If they are trying to hook you by talking about exploding revenue, little to no work, passive income and other terminology that make it appear as if all you have to do is sign up, pay the minimum fee and the dollars will start rolling in, then avoid it. No business, MLM included, is easy in this sense. You might have a passion for one type of work over another, and enjoy this but not that, but no system is going to be passive or have exploding revenue.

It is going to be a lot of work to build up your network and distributor system. If they try to sell you on their system saying their is almost nothing involved, stay away
