That's probably true, but there's a pretty wide variety of algorithms (especially in those overlays that use superpeers) for deciding on promotion criteria, and I think the decision is made by existing members extending invitations in quite a few of those algorithms. I don't think it's something we can/should prohibit at the peer protocol level. Seems like it should be a decision of the DHT algorithm.
