Hey all. There are a few things being raised here, and we'll cover each, in some way. There's the exploit itself. There's us NDAing content creators and the responses from Mod Bolton. There's the idea of any collusion between Reddit and Jagex.
In terms of the exploit. It's standard to not discuss active investigations and actions being taken, at least until after we've taken steps to resolve the issues. We became aware of a method being used to duplicate gold, and a combination of things - including tip-offs from Rendi and our system monitoring - led to us becoming aware of it very quickly. The Support and anti-cheating teams worked on removing a large amount of gold and investigated the accounts involved, whilst the SysAdmin and Engine teams were working on stopping it happening more. We remain diligent, and are yet to see any repeated occurrence of the exploit - work is continuing to improve our game systems to prevent this sort of thing from occurring again. In response to Rendi’s tip-off specifically, we were (and remain) very appreciative of his tip-offs. The video doesn’t seem to cover any of the other interactions that occurred between him and the JMods in the server in which we did quickly acknowledge his tip-offs and did thank him for his vigilance.
There's no collusion or conspiring for suppression with the Reddit admins. We don't astroturf or censor posts and we will never do that. It seems that they independently took action to prevent information sharing of replication steps for duplication methods. I'd presume that they were acting entirely in good faith, and did so to prevent knowledge of the bug being made public and risk its further abuse. If that's the case, then I think it's because that they think it's better if everybody doesn't spend their time duping cash. I don't think there was any malicious action.
In terms of NDAing the content creators. This is entirely separate from this specific game issue. Mod Bolton is the Head of Influencer Management, and he tried to reply to this thread at 7:07am to explain, though it looks like his comment was auto-hidden! I'll reply to my comment with his message.
*edit - Bolton's comment has now been unhidden, you can find that earlier in the thread*
If you have any other questions, please do reply and ask them.
