i think the issue here is how the people from MLM "sell" their products to other people... the public would not criticize if those who posted here don't post offensive and degrading words to those who would ask and clarify what the product really is...
try to look at kekerouno... he's selling his UNO brand to the public, just like waht elmariachi is doing, and theyre both in MLM business, but the problem is, kekerouno is badmouthing elmariachi's product, which if we would really think, is about the same system and the same "oppurtunities" as to the AIM's system.
what irked the people here is how those who "market" their products, in an offensive way...
if thats how your system works, then thats how you live with your creed, but not to the point of saying lies, false hopes and threats to those who would want to know the real essence of the business.
