I think it's important to note that:

What i dont think is right is that he is encouraging illegal activities. Which I dont believe is illegal.

So sorry KaptCrunch, but i think the only thing you would be able to report him for is theft.

O btw: That looks like a AWESOME little recovery tank Xenon. I just have 2 questions:
Why would you not pressure test it before vacuuming it out? Is it just assumed that your tap will have no leaks and the tank will be able to hold decent pressures?
And will one of those be able to store all the refrigerant in a typical phase-change system or will I need like 5 to recover all refrigerant from one system?
