It seems there is some clarification required how the epvp staff moderates this thread. Please note that our moderators only apply the official epvp rules, no thread specific rules, however, the rules specified by Coach Broeki (OP) almost align with our rules with one exception.
We allow scam accusations if the following two requirements are met:
1. If the accused seller has an thread in our black market, the feedback must be posted there, not in this thread.
2. If you don't have an active trade request with the accused seller, you need to include evidence in your post, if you don't have proof, we will definitely delete your post on-sight without any questions asked.
We still suggest you to follow Coach Broeki's guideline from his first post in this thread, just to keep things orderly going.
