For those that was there and tried out RS5 shortly after beta went live, you know that there was bugs and exploits that could be used to gain millions and more millions. As it is beta and we want everyone to find bugs such as these, we dont really care about it. If you got millions from these bugs, have fun with them on RS5.
However, it has come to our attention that some players are trying to sell RS5 money for RS4 money. This is not tolerated as the RS5 money was gained by exploits and should therefor not be used to gain money on RS4. Anyone found doing this will be banned from the RS5 server and most likely assets stripped off on RS4 to cover for what that player has 'gained' on this.
