A person I'm vaguely acquainted with runs a web store as a solo venture. She was in a traffic accident and injured badly enough to be unconscious for an extended period of time and unable to do anything with the website, it kept selling product until everything registered out of stock and eventually she was able to shut the site down (no idea how the merchant account didn't get suspended in the 5 months or so as nothing shipped and obviously there was no response to any charge back)
