Selling recipies above the ingame price

I think it should be made impossible to sell dropped recipies above the ingame price. I still see every day seller ripping off fellow players in cs. Not all players read the forums and spend unknowing to much credits this way. Imo this scam has to be stopped.

i agree, its kind of ridiculous, maybe you could go to crafting vendor and "hand in" recepies for like... 1k lower than the game price or something and are not allowed to be put on cs
