The dude from feedback told him it was his fault for not reading about some bug which I have not seen anywhere being mentioned. From what I understand feedback is supposed to be above even Wryom since he will tell people to take things up with feedback.
Unless Retser did personally pull this dude aside and said what he was doing was abusing a bug and that's why I can't find mention of this anywhere. And yes, if that's the case I would totally say the OP is 100% wrong if he kept doing it after that.
