As far as I understand, some of the Nodes netted quadrillions of silver in taxes to node owning guilds, which then got collected by guilds or a part of those (people got kicked from the guilds to yield more Silver for the minority of the chosen ones).
Obviously all of that silver was used to buy top tier gear from the marketplace, while GMs were catching up to this issue.
Few hours later marketplace was shut down and exploiting accounts temporarily banned for investigation.
Later marketplace was reopened. Whether all accounts related to the withdrawn silver were locked or not remain unclear as of now. Punishment measures, if there will be any, were not announced as of now.
You can stay up to date on this issue by visiting the official NA thread OVER THERE.
Maintenance was announced that should (don't quote me on that, it's not my claim) resolve this issue.
Along with that a bit of clarification was posted regarding the issue:
- Issue was caused by packets manipulation. All accounts associated with those manipulations will be permanently banned, and rightfully so. On that note - the possibility of client-side manipulation of node taxation is kinda stupid, can't think of a better word.
- All other guild members will have their silver withdrawn. The exact details on "how?" were not provided (what will they do with items bought using this silver? if they'll just put a negative number in those users' marketplace warehouse - that clearly will not solve the issue completely). All of the affected guilds members will be under further investigation (as far as I understand this means that GMs don't plan to ban all of them, which is good IMO, but some might get banana if they were involved somehow, albeit I have no idea how they plan to investigate that, interrogation?).
- All Valencia nodes taxes will be reset to 0 during maintenance.
