Just so everyone is sure on our policy with duel scams the current policy (which is subject to change) is as such:
I) The opponent timed out of the server:
No refund.
II) The opponent purposely quit the duel before loosing:
No refund, but inform a GM if you have a screen shot of them quitting and it's obvious they did it on purpose, the GM will punish them if they think it's a good idea.
III) The opponent set up the server with a mod that made it so he'd win every time (or at-least the vast majority of the time):
If you provide evidence (use /set to get the settings and use page-up and page-down to scroll through them, screen shot the settings and mod name.) you should be refunded, and the opponent will be penalised by a GM or Smod.
In case II or III you can contact a GM or Smod as needed via PM, in case III you can also post the information in the scam reports board in the market forum.
Note: the reason no refunds are given in case I or II is for the following few reasons:
1) Both players loose money, not just the person who timed-out / quit.
2) There are so many of these cases and typically they carry with them very little evidence, by responding to them the staff risk aiding more scams than they fix.
3) The risk of a ping-time-out is considered part of the risk involved with gambling, in horse racing you risk your horse catching a horrible illness, this by example is analogous to you or your opponent timing out or quitting.
Note: As is the case with most policies, the staff can chose to follow the policy or ignore it, this is what the staff will typically do, but not always.
