Why some countries banned Qnet?

In some countries, authorities described Qnet as a pyramid scheme, a scheme where people who join first make money then the ones who join later make less money, and as a result, it was banned.

Some countries such as Sri lanka and Iran banned Qnet for resulting in sending a large amount of money outside the country in the form of product purchases. 

In some countries such as Rwanda Qnet was accused of the violation of tax laws. The problem was resolved later on.

Qnet is a highly controversial company that results in strong debates between people. This controversy forces some governments to intervene.

In some countries, Qnet was believed to be a source of harm to the economy, and as a result, it was banned. (See Is Qnet a scam)

Some governments banned Qnet after claiming that the company provides low quality products that aren't worth the money people pay. 

When Qnet enters a market successfully it becomes highly popular. This popularity leads to controversy which sometimes leads to problems with governments.

Qnet usually results in raising loud, angry voices in each country it enters. Depending on the power and the influence of those angry voices the governments might respond with a ban.

Some government officials believed that Qnet is a scam and as a result they had to ban it. (See Why do people fall victim to scams?)

In some countries, officials complained about the fact that Qnet representatives, people who join Qnet, can fully avoid paying taxes.

In some countries, such as Egypt Qnet was considered forbidden by Islamic law. While this didn't result in a ban, it added to the controversy surrounding Qnet.
