Wow, the snark is real.

We don't allow it for more or less the same reasons rscrevolution didn't allow RWT. http://rscrevolution.wikia.com/wiki/Real-world_trading

Andrew Gower, one of the co-founders of rscrevolution and the original developer who created rscrevolution, pointed out that introducing the ability to engage in real-world item trading significantly modifies player behaviour and puts players with access to significant "real-life" financial resources on an unfair footing with other players, distorting many aspects of game play and changing the relationship between the company and players. As a long time multi-player game player himself, Mr. Gower saw the impact of real-world item trades and how it changed the behaviour of players who obtained these items in other games.

We have this rule as part of our procedures to preserve the integrity of the game and its players' hard earned achievements. The hiscores are there to measure the achievement of an individual, not a group of players or 3rd party. In the event that a dispute arises over account ownership, we will always side with the original creator of the account. This rule which has been a part of rscrevolution since the very beginning, to fight the commodification of player accounts.

people are already doing it behind your back
