Like HB staff said, they have a new "warden guy" at Blizzard who knows what he's doing and wtfpwnz them now. So I was thinking if multiboxing manually could be an option for making $? Like the player limit per node is 10, right? So you can get 10x times more herbs! The only problem is click broadcasting across windows is quite annoying. So you'll still be slow if not slower than a bot, but still an option, right? riight? What about non-invasive simple fishing bots/scripts? Fish goes for good price. I'm talking about that one free external bot that evaded both latest banwaves.
Check the multibox forums, I believe one dude is/was doing it with 5 chars. Making insane gold and selling it.
Is it open source? I've got some # and ++ exp so I could take a look I've been doing it with 5 chars for a few days. Problem is that node click broadcasting is a pain in the ass. And it slows you down a lot. Idk maybe he's got a better way of doing it. But also my eyes started to bleed out after 10 hour gathering sessions from having to look at the damn minimap constantly looking for nodes.
Yes, there is one that is open source, a passive bot coded in CSharp. Look around on the other forums.
