DO's
1. Do check out the forums to see if people are getting paid.
2. Do email the admin to check for bouncing address.
3. Do monitor game for about a month, before parting with your gold.
4. Do try and resolve a non-payment problem with admin before shouting on the forums, they could have made a genuine mistake and doing so could stop new spends, which might affect future payouts.
5. Do remember most are just games, don't spend too much too quickly, maybe use a percentage of your spending amount.
