I think the community is on its own for this one.

For the bot-type originally discussed at the start of this thread, one I will call the Market-Crash-Bot, a suggestion that might be useful is to coordinate with other sellers in your world to each take a set of, say, 5-10 items cornered by the bot and to undersell so that the bot can't sell and profit for RMT. My experience is that the bot sets its price floors to the cost of mats, and for poly-DOL/DOH players, this should be easy to beat. These sellers will have to take one for the team (the server) to let the well run dry, but I don't think it'll take more than a month to eliminate the bot if profits aren't coming in. The RMT merchant will probably bot something else, like crystal selling, but I think the market bots are the most damaging to the health of a server.

As I said before, I'm quitting after my sub lapses at the end of the week, specifically for the poor support for bots and fair play. I also have to say that SE USA's support has been pretty pathetic, and I don't really want to give them any more money. We haven't even received a form response on the forums or an acknowledgement of the issue. With email, I only receive template emails that don't address my message comments. They don't have to tell us whether or not they're investigating specific bots; they just need to at least acknowledge that they've received the issue.
