Microsoft has banned "a small percentage" of Xbox Live users found to be in possession of modified Xbox 360 consoles.
While the platform holder didn't release specific figures, the Guardian reports that the number of users affected ranges from 600,000 to one million. Xbox Live had over 20 million active members across 26 countries as of May 2009.
The report suggests that the most recent wave of bans is part of an annual sweep carried out by the platform holder to stop modified consoles, which enable users to play pirated or imported titles, from connecting to its online gaming service. The bans don't stop consoles themselves from working.
"All consumers should know that piracy is illegal and that modifying their Xbox 360 console to play pirated discs violates the Xbox Live terms of use, will void their warranty and result in a ban from Xbox Live," Microsoft said in a statement.
The Entertainment and Leisure Software Publishers' Association has suggested that piracy may cost the videogame industry as much as £750 million a year.
