500px uses automated detection methods to identify and remove AI-generated images from its platform, including from Licensing, Quests, and public profiles, and enforces a zero-tolerance policy with permanent bans for violations. The policy was publicly articulated in February 2025.

A February 2025 official 500px blog post states that the company is 'continuously enhancing our detection methods and enforcing strict measures to prevent AI-generated content from being shared on the platform.' The platform bans AI-generated content from Licensing, Quests, and public profiles, with confirmed violations resulting in permanent community bans. The company also asks community members to report suspected AI-generated content for human review. The specific AI detection tools used were not named in the source.
