Just because someone posts 300 stacks of material X in one whack doesn't really mean they got it from botting. I've done this, or close to this, many times. Most people despise farming and I can certainly understand the lack of appeal, but I don't really mind it. I have nights where I just go to a random area and farm the crap out of something just for the fun of it. I then send everything I farmed to my bank toon. After you do this a few times, you end up with quite a few stacks of things that you eventually dump on the AH. I guess my point is that just because it throws up all the red flags of a gold farmer doesn't mean it is one, and theres absolutely no way to tell one from the other. Unless, like previously mentioned, their name is some random combination of numbers and letters.

Also, I've noticed that most of the people advocating the "if you don't buy it your competition will" argument are getting replies like "So don't compete". It just doesn't really work like that. If you play the AH game to make gold the very nature of what you're doing is competing. To not compete would be to stop playing the meta game entirely. I personally enjoy playing the AH game, it's a big part of the reason I'm still paying for game time. Why should I have to stop just because I might at some point have supported a gold farmer but have no way to tell when I did? If there was a clear way to determine who is a gold farmer and who isn't, I'd be all for only supporting those who aren't. But since there isn't, I see no reason for it to ruin the fun of others.
