His mother, Jennifer Zdenek, says that Xbox Live was some of her son's only social interaction outside of school. She told a local news station that her son was devastated when he turned on his Xbox 360 and discovered that his Gamercard had been branded with a Scarlet Letter-like "Cheater" tag and that his Gamerscore had been reset to zero.
In a story on Seattle's Q13 Fox News station, Zdenek says she tried to contact Microsoft but only got a form letter response. Q13 said they also tried to reach Microsoft but received no response.
Microsoft did eventually step in and investigate the specific case, and it stood by its decision. In a post on Twitter, Director of Policy and Enforcement for Xbox LIVE Stephen Toulouse wrote, "We confirmed there were cheated achievements and gave the parent the details. This wasnt a 'he played too good' situation at all."

I stand with Microsoft. A Cheater is a Cheater is a Cheater.
