Holylightband farming gold in balefort hidden passage using bots. I lured him into the main entrance where there's nearly no enemies that spawn. In the video you can see him repeatedly shooting skills when there's nothing there. I have seen a number of players using bots to farm gold lately. If done over the course of several hours or even days, a person can make hundreds of thousands of gold that they didn't rightly earn.
I witnessed his actions over the course of several hours. Same result everytime I went to check on him. After hours, he finally responded to messages and chats, calling Boss and I noobs and idiots and claiming we have "noob jealousy" apparently because we don't use bots.
From a PVP perspective, devs may not lose money if people bot their way to leaderboards, so they may not have a reason to do anything about it. However, from a PVE perspective, someone who farms gold through botting and liquidating thousands of drops will use that gold to buy the most expensive pinks from CS. The more people who farm gold or even gain xp by botting, the less platinum that will be spent on elixirs such as Shamus in hopes of getting a good pink or Thrashers in hopes of achieving the highest level by playing normally.
