No, you're correct. There WAS a sub-forum where people could advertise stuff they wanted to sell. The PMG, being a very sophisticated AI and Digital Overlord, has co-opted that page into his own programming. Now all the stuff that people advertise gets funneled right to him. He sorts through it all, purchases some of it to recycle into his growing robotic army, and sells the rest to fund his operations.
