With the system working as expected for a while now, I haven't noticed anyone making crap posts to generate things. For the most part you are rewarded pretty well and most people don't want to spend too much time doing it.

Back to the other part where you can buy things from the forum for the server, we were working on it but ran into a huge road block. We may have to revisit this later when we have more time to work on a big addon like this.
