Dissatisfied customer

[Dustytome]

(That is not to say it won't irritate vendors)

From the stories showing up on reddit now and then I'd say SE doesn't like being irritated. Some banks/card have automatic double-charge protection and since the mogstation doesn't have a cart system, buying multiple of an item resulted in that double-charge protection kicking in and the customer's account getting banned. Just make sure if you go that route, you truly intend to be done dealing with SE.
