Indonesian TVI Express blog explains how TVI Express is a Pyramid Scheme

The blogger though, describes it as if it is legitimate, but is it? Let's see what he wrote:

Or restated: once you join, you must make as many people join under you as possible, and make sure all who join under you also do the same: make more people join under them as well.

Not a word about selling anything, just recruit, recruit, recruit.

Why is this NOT a scam?
