Donald Trump would be endorsing ACN if he thought it was not a legitimate company. There are many people in the multi level marketing industry who are utilizing MLM as a way to cover up pyramid schemes. In every field of industry there are people who don't play by the rules and try to take advantage of all others involved. I don't see why this should be different for network marketing. There is good and bad in all the people, things and businesses that you will experience in life. Don't base your decisions on opinions of negative people.
