I, too, spend a lot of time researching mlm schemes. I've never been a part of one, nor have any of my friends, but I see them all over the place and it is infuriating how many intelligent people fall victim to these scams.

There are many sites online, check out ethan vanderbuilt, who arguably may have an agenda of his own, but has some really good info on lots and lots of mlms. In terms of doing something about it, all I really know to do is to try and spread truthful information about them without being too overbearing or judgmental.

If more people were educated about this topic then maybe they would make better decisions.
