A Skyrim username error involving one missing underscore sent Brandon Klayme, an innocent man from Halifax, Canada, to prison for 18 months. The mistake was small enough to overlook on a screen and serious enough to survive police work, prosecution, a trial and sentencing before anyone caught it.

Klayme was ultimately acquitted after his appeal lawyer reviewed the original request for account information. By then, he had served his entire jail term for crimes the Nova Scotia Court of Appeal said he did not commit.
