Hi. Im not trying to act/be a mod just making saying.
As of the new updates in Runescape as of the GP/item trade limit, there is NO more account buying and selling for gp. If you haven't seen on rs lately there are many new updates to stop the real world traders (if you want to read more go to www.runescape.com
The only way to sell accounts on here is for IRL cash or trade as the max is 30k you can give for an account therefore there is no point.
