What Can Happen If You Use Your Ally Checking Account As A Business Account

A Bogleheads member described how Ally Bank closed his checking account when Ally discovered he was using it for his business. In addition, he reported that Ally is deducting all interest paid to date since the account was opened. As one of Bogleheads member replied in that thread, Ally Bank's account disclosure does mention this restriction:

Interest Checking accounts are only available to consumers for personal, family and household purposes. You may not use an Ally checking account that earns interest for business purposes.
