Giving Free trials trade is a bad idea. RMT use throw away accounts for advertising, moving gil and items. These accounts have subs that are paid with time cards, the cost means little to them of course. But giving free trials trade will allow RMT to ditch the time card cost and expand the number of throw accounts they have by a massive amount. It would become a throw account paradise for RMT's, if your intent is too make the RMT problem worse your on the right track.
