This whole seller's remorse theory is weak. Just look at IGE. See how much they'll pay you for gil and compare it to how much they sell it for. Of course IGE itself didn't steal the account. But then, IGE itself doesn't farm gil. There aren't IGE employees all throughout the server. They simply buy and sell. I doubt they ask too many questions. It seems obvious to me someone else had access to his account, or someone who had in the past had access new some sort of financial information required to get the password retrieved. As stated recently in this thread, his PoL ID was known at least in November. Now you can change your password but you can't change your ID. Of all the possible explanations, this is the only one that makes sense to me.
