Arcade game machines have evolved to include player-generated content (PGC), allowing users to create and share their own levels, characters, or even game modes. To maintain a safe and enjoyable environment, developers incorporate moderation tools to oversee this content.

1. Automated Filters: Many arcade games use AI-driven filters to detect and block inappropriate language, images, or behavior in user-generated content. These systems scan submissions in real-time, flagging or removing violations before they reach the public.

2. Community Reporting: Players can report offensive or harmful content through in-game tools. Moderators review these reports and take action, such as removing content or suspending accounts.

3. Approval Systems: Some games require player-created content to be reviewed by developers or trusted community members before publication, ensuring quality and safety.

4. User Ratings and Feedback: Games may feature rating systems where players vote on content, pushing high-quality creations to the forefront while burying low-effort or inappropriate submissions.

By combining these tools, arcade game machines foster creativity while maintaining a positive gaming community.
