Researcher banned for 10 years

The American Society for Microbiology, having retracted several papers by a Japanese researcher because of image manipulation, has issued a 10-year ban on the author from publishing in any of its journals, according to Retraction Watch and Science.

COPE does not recommend bans on authors but this topic was hotly debated at our US seminar and seems to be getting more common. We'd be interested in your thoughts.
