Skorpionek is a part of our alliance (Polish alliance on Deli), but I wouldn't say he's a part of our "bulk group".
I don't think anyone in our alliance knew about the way he's doing business (so far everyone is surprised that he's doing this thing with mail). We don't consider buying things cheaper and selling them for higher price as something "unfair", but as I understand that's not the issue here.
Let's call him and see what he has to say: @Skorpionek.
Oh, and as a fellow Wurmian, I'm sorry it happened do you guys. Of course we'll talk with him on our ally chat.
Edit: And he didn't log in 5 days - in case anyone else waiting for him to pick up mail.
