Initiatives to maintain soundness of Mobage

Since the Mobage service began in February 2006 it has been supported by many users. For the operation of this service DeNA defined the Mobage usage rules and built a system and human-based monitoring structure to enhance the soundness of the service. DeNA has also engaged in educational and awareness-raising activities, including providing educational content and holding seminars at schools to raise awareness.
Going forward DeNA will continue to enhance initiatives to maintain and enhance the soundness of the site for the protection of young people.

Mobage Usage Rules and Initiatives to Enhance Soundness

1. System Measures

• Advance post blocking system Highly malicious words are blocked by the system so they cannot be posted
• Keyword monitoring system If a post with words that violate the rules is made or sent, then the system automatically sends a notification to a member of the patrol team
• Bayesian filtering (In place from December 2007) The system regularly learns from past posts that violated rules, and automatically detects posts with a high chance of a violation
• Minimail (message sending function) usage restriction (from December 2007) System automatically blocks anyone under 18 from messaging a user whose age differs by 3 years or more (+supplemented by human monitoring) *Users under 13 are completely prohibited from using minimail (from December 2007)
• Minimail usage restrictions between particular users (from August 2009) If particular rule violations are confirmed in the use of minimail, then restrict the use of communication functions between the sending and receiving users
• Usage restrictions for Mobage chat based on age (from November 2021) Restrictions are in place to prevent users under 18 from using Mobage chat

• Visual checksPosts that the systems detects may have violated the rules are all put through a visual check, and staff members take necessary measures such as providing guidance to users, imposing penalties, and revoking memberships
