To be honest, there isn’t anything to search for. You’ve done all you can and all that you need to do, the rest lies in Blizzard’s hands. As Perl said, all you guys have is your assumption they’re doing something wrong because they’re an aggressive seller. There is absolutely nothing wrong with using multiple toons to go ham on the AH. The only thing in that that would be illegal is if they’re using some sort of illegal software/hardware to control the toons.
While investigations do take time, they happen in Blizzard’s time - not ours. You guys are so sure they’re doing something illegal, but it could very well be that they’re not, which is why they’re allowed to continue on as they are without sanction.
I have two or three AH toons I shuffle between on each of my main servers. I’ve got a fairly good relationship with most of the other folks who like to corner the legendary market, while we do always cycle through listing and relisting for who’s at the top, if we see one another on, we kind of let the other get some time to sell before we go about the cycle again. But I’ve sat there at times, afking and just staying logged in to work it. No botting, I just manually log in and out between toons because I’m not quite as vicious as the person on your server.
Now it may be that you guys are fully in the right that this person is doing what they shouldn’t be, but they could just as well be minding their own business and rocking the AH harder than you guys. And there isn’t anything against the rules about that. People would be surprised how hard some people play the AH game, and they do it within the rules and regulations set down by the game.
Either way, you guys reported them. That’s all you need to do. Go on and play the game and if they’re still there? It’s not that Blizzard is ignoring you. It’s more than likely that all of your assumptions are incorrect.
There are a number of threads just like this one where people have come here in their frustration that ‘nothing is being done’. Posting a response from Vrak:
