A new Version of Warden was released with 3.3.5 Most hacks no longer work.

Uprate Nihilim's comment please. I've found no evidence for my statement other than unsubstantiated rumors, and multiple sources confirm Warden 2.

Yay!

Nihilas is correct. A new version of Warden has been released which detects many of the common ways that botters do their work. There is also speculation that metrics such as time-in-zone have been added which can draw admin attention to likely botters. However, some continue to bot despite the increased risk.

From my own experience, I have noticed a marked decrease in the number of bots herbing in the basin in the last month. Up until then, I had been constantly logging tickets with support to report these bots. It literally took from Jan to around the end of May before I finally noticed that the most frequent bots were now gone. It does seem that Blizzard finally took action on these bots, whether through a new Warden or other means.

I know for a fact that a large amount of herbs that I purchased off the AH were sourced by bots. I admit I had some ethical concerns about buying supplies from the people I was trying to shut down. In the end, the need to cut off my competitions supply chain won out. However, I am very glad to see the old bots gone, and I'm more than willing to compete against the other sellers not only in the AH, but also directly in the basin.
