I'm sorry to hear that you were the victim of a scam. However, the Forums are not the place to report this.
If you find another player breaking the rules of the game, that should be reported using the in-game ‘Report Abuse’ feature, at the time of the incident,so that Jagex will have evidence needed from their own systems to take action against the rule breakers.
You cannot accuse other players (or clans) by name on the Forums, as there is no way to provide the necessary system evidence here, and there is no way here to determine if the account being accused is actually under the control of the account owner, or if it has been hijacked.
