Pimp problem

[RPesse]

Well, maybe it's me that's too naive to understand but when I first heard about the pimps it was on this forum some days ago. Today a player pm'd me and this is what he wrote me and I tried to understand better.
It's illegal, right? I'm trying to investigate this thing and I would like to know if any other girl (or boy, I don't know if it involves them too) had this encounter...
