No it isn't. Imagine that A convinces B to sign up.

A pyramid scheme pays "A" with the signup fees from "B". If people stop signing up, then you can't pay B.

Here, "A" is paid IFF "B" makes money. if B makes no money, then A makes no money. It's revenue sharing from referrals, not a pyramid scheme.
