Since a few days, on Ragnarok, someone decided to try and crash the Culinarian market for some reasons.

He's basically selling insane amount of 2stars HQ food to the point you're losing money if you're buying mats off AH, or you'd rather sell the raw materials if you're gathering them forcing me and some fellow culinarians i know to buy his whole stock in order to avoid a crash of the market.

We attempted to talk with him, however he only connect to craft in "busy", preventing any tells and/or any other form of communication, also ignoring whatever we say in the /say chat.

We also attempted calling a GM as this kind of behaviour sounded extremly suspicious, to what they answered player were allowed to play with the market how they want.

Are other servers affected by that kind of plague as well? Is there really nothing to do to stop this kind of player? I'm personally losing money everyday and cant sell my stock because of this single player...
