Bepules, first of all, I think your accusations are void. The devs do not pass such information, at least not that I would know. I remember selling an iron battle axe just a few minutes before the server restarted and the slash was decreased, however, that was just chance. As far as I know, chainmail and silverweave things have been sold constantly, not depending on the date. In my opinion, it isn't remarkable that someone sold his things one day before they became available to everyone, maybe he was simply in need of money.
