Is this internet scam illegal?

So recently i made a deal via email
with an individual to acquire his clash of clans account for x amount money. If you don't know what that is, think of it as an account for any iphone game. What happened next was, the individual said that to keep things simple I should send him the payment as a gift through amazon to his email. I complied, and did so. Once he had received the payment, which technically was a "gift" through amazon, he stopped replying completly. Is there any legal action that can be taken if I know he lived in the US like myself? Also it should be taken into considerarion that selling accounts on clans violates their user agreement, so i guess he could use that as an argument. Thanks! If you don't know the answer a forum where i could ask a cop or someone would be great!

FINANCIAL REFORM
Tax havens contain over 20 trillion dollars, the banks profit without producing very high volumes for the economy and speculators profit only buying and selling.
With this money you can build vertical farms, infrastructure, power plants and pay the debt of governments

You can't do anything about it.

An agreement was made, you did your part, and he didn't do his part. You can sue him for the item or to return your money. You'd have to identify his real name.

You can call the police and accuse him of fraud. Most likely the police will do nothing because they have a lot more important things to keep them busy.

The game company does not make the laws. They are making their own policies. The company's policy of no selling accounts does not make the fraud legal. It just means that the company is not going to help you or get involved with it. You might be able to call them and complain and the account would get banned… So in a way you would be punishing the person but he still has your money.

Realistically… Nothing will ever happen and you have just lost a little money and learned a valuable lesson.

Don't ever just wire money like this over the net to an person, thats scam 101 and consider it a lesson learned.

"Also it should be taken into considerarion that selling accounts on clans violates their user agreement," So if you know that why would you enter into an illegal agreement with him? Because you thought you would get money… If it sounds too good to be true it generally is too good to be true, greed and illegal activity, learn from it, report it via Amazon as a scam and don't get pulled into scams in the future…
