I know many players are young children, and I think you need a better understanding of the word Scam, which people are always shouting about in Hollas.
A scam is when someone says that they will give you, say, a car, for 3,000 cubits, and then they take your money and don't give you anything, or say that now you need to give more money to get the car.
If some one says they are selling a car for 1,000,000 cubits, that IS NOT A SCAM. It's just someone setting a ridiculously high price. You are not required to buy the car, so there is no scam involved. If i sell an Hat for 1000 cubits, and Joe sells the same hat for 100 cubits, I am not scamming you. I just have a higher price. Be smart and buy the Hat from Joe and don't whine about being scammed. You weren't required to buy anything so there was no scam.
If you don't want to get scammed, DON'T GIVE ANYTHING TO ANYONE EVER. Use the trade option and make sure you understand what you're getting before approving the trade. Same goes for vending machines. The machine tells you the number of items and the price. Make sure you understand what you're getting before paying. No one can force you to trade or buy items. If someone refuses to sell an item to you there is nothing you can do about it.
Finally, whining is useless and solves nothing. If you feel you were actually scammed, report the person who scammed you through the report icon. Because, personally, I am SO tired of all the whining that takes place on Hollas.
