The normal thing to do would be to pull him aside and have a chat, and maybe take off anything earned that was deemed excessive. This is really in that grey area between true GMA and clever use of mechanics. When I think of GMA I think of infinite scrip glitches that we had, and silver ones, things like that. This is more convoluted, and more akin to creative farming. The fact that they had to have internal discussions about it in itself shows that it was really more in that grey area. Naturally they could have ultimately decided to clamp down, and that's fine, but it could have been handled in a much better way. I don't know why they so often default to the position that the customer is their enemy and needs to be punished. I'm pretty sure had they just had a normal conversation with him and told him to cut it off, and took some of that silver off, that would've been the end of it.
