I thought I talked about this problem about it already through teOx while you were away, or did he forget to pass the word I guess?
Like I told teOx, as of this moment, your statements about another player is as valid as thin air without any sort of evidence backup. You have to realize that in these unsupported accusations, GMs are technically not obliqued to do any follow up for it. Please make it an important lesson (I believe your guild already told you about it too) to always be careful with trades, transfers and especially account sharing. Always take screenshots when important valuables are at risk in trading. "Scams" in trade windows look very much like genuine trade between friends within the item logs, and it takes a great amount of effort to have to match up the chat logs (not to mention, server suffers intense lag when Pandora uploads the logs for GMs to check them.)
We'll see what we can do, but there's no guaranteed promise, especially specified punishments against another player as 'requested' by poster, on any results. We'll decide by what we find, if we do find anything.
(By the way, preferable if you send in a Support Ticket for this type of matter in the future instead of PM+forum thread. Not only is it more secretive and something GMs always check, but also there are occassions where the players at fault sees these threads before the GM, and go on to "fix" the problems before the GMs can get to it.
