RuneScape developer Jagex has fired an employee for abusing moderator privileges.
The studio revealed a member of the Old School RuneScape team, which runs a self-contained version of the popular MMO game based on the original 2007 source code, had been moving wealth and items across accounts.
"During our rigorous routine system checks, irregular activity was identified on small number of accounts, including the movement of wealth and items back into the live game," revealed Jagex.
"Following our investigation, we were able to resolve the issue before any significant impact was made to the wider game, or economy. We have also taken steps to return items and GP to any affected accounts."
Jagex is now working with the police to resolve the incident -- highlighting the serious nature of the situation -- and won't be able to provide further details until the matter is resolved.
"We pride ourselves on the passion and integrity of the JMods that work for Jagex and we hold them to the highest standards. However, we are not afraid to take tough action and make difficult decisions if someone cannot meet those standards," added the studio.
"We will dust ourselves off, and move on. Old School is at its biggest and strongest since launch, but we still have much to do, not least a mobile launch which each day gets closer."
Update: A Jagex representative also contacted Gamasutra to give the following statement:
"Further to yesterday’s announcement, we can confirm that none of our players’ bank or card details were compromised. We work with an industry-respected, fully compliant third-party payment processor, to purposefully avoid staff having access to players’ full bank or card details. This also applies when players choose to save their details at payment stage for any future purchases. Jagex undergoes regular, third-party testing to ensure we maintain the highest security standards."
