Microsoft's newly launched Xbox Entertainment Awards service has reportedly been hit by a security breach.
MCV was contacted by a reader with a link to a page seemingly listing the names, gamertags, emails and birthdays of all those who had voted.
The site reports that those accessing the website were able to edit or remove listings.
Voting has been suspended and the awards website is currently offline for maintenance.
Microsoft said in a statement: "We are currently experiencing technical difficulties with the Xbox Entertainment Awards landing page and have taken the site offline while we investigate."
Launched yesterday, the Xbox Entertainment Awards asks fans to vote for their favourite products across a range of categories including games, movies, TV and music.
