A post to the Battle.net forums complains of another exploit being used to gain experience in Diablo III at an unusual rate. It Details about exactly how this works were deleted, but it seems to be taking advantage of a bug in the game code. Blizzard is in the midst of the game's first competitive season for the action/RPG sequel, and this impacts leaderboards for that, so it's not clear if there will be some effort at remedying the situation, or if they will just patch the exploit and allow those who took advantage of this to benefit like they did with last week's exploit. A support agent has responded to the thread saying they are currently investigating the issue.
