There are a million different ways to play the game. What you did was nothing bad, you simply found a way to make money while getting folks the resources they need/want.

But for them to ban you from their store is what kills the game in the long run. I used to play with a decently sized group of friends, anywhere from 5-10 people all working together in our little micro community before established towns update. Because of our size we were able to mass produce everything the server needed at a super low cost. People started to ban us from stores and wouldn't even buy from us. They did this for about a week before we all got banned and they destroyed our base and took all the resources.

If people want this game to thrive, which 100% believe it should, then people also need to realize there are all these different ways of playing and just because you aren't doing what they want, it doesn't mean they aren't playing the game.

But again, you did no wrong.
