Today more than 3,700 Guild Wars accounts were banned. Those terminated were positively identified as botters or players engaged in PvP match manipulation. We also disbanded whole guilds that were involved in these activities.
We take this issue very seriously and have worked to improve our methods and tools for dealing with exploits like these. There are consequences if you engage in botting or match manipulation.
Our Design Director, James Phinney, has provided more information about the bans and about our plans for continuing to pursue those involved in exploiting in his most recent blog post. Head over here to check it out.
