You should also start looking at the bigger picture and figure out how you're going to prevent these type of things from happening in the future. You can't just reset everyone's bank account every time someone glitches money into the server. That's just not fair. There are probably many people who are rich because they worked hard for it, and probably weren't in the loop with this glitched money, and now they are possibly going to lose all their money simply because there is no efficient method to containing glitched money.
