For sure having interactions is always nice and all, but there is no way to guarantee that people follow what they said. For example, you could just have kept all the goo to yourself, giving them nothing in return. That why our corp closed the fleet to the public, too many free loaders. We wanted to give new players an oportunity to make some isk and try the mining career, but some of them were too greedy (not all of them though, we got some new members out of that)
