After the launch of first expansion Mines of Moria, Turbine has posted a notice about gold selling within Lotro Gold on the official forum. It reminds me an old fan-made video on the Youtube and maybe you had seen it before.

The details of the notice are as below:

Gold farming, gold selling, gold spamming, gold buying, powerleveling, account sales and purchases, or purchasing items with real-world money within the Lotro Gold are called Real Money Transactions (RMT) and are strictly forbidden on all of our servers. Any time you pay real money for a service, item, or currency, you are violating the Code of Conduct and may be subject to disciplinary action. This can range from a warning to a permanent account suspension. These penalties are harsh because these actions affect significantly more than just your account. Purchasing gold or powerleveling directly contributes to the continued spamming of our game by these organizations, and to the continued farming and exploitation of our game items for their profit.

Purchasing gold or powerleveling directly encourages and supports the farming and spamming of our game.

There are other reasons not to engage in this. By purchasing your way to the end, you devalue the efforts of your fellow players and seriously damage the fun of playing the game. Additionally, you put yourself at risk of theft from risky websites and organizations; the majority of our compromised accounts are a result of visiting websites or engaging in services of this type.
