What are the current best practices for handling user-generated content (UGC) in web applications to ensure safety and compliance with data protection regulations?

Handling user-generated content requires robust moderation systems to filter inappropriate content, mechanisms for users to report concerns, and compliance with data protection regulations like GDPR. Best practices include implementing automated content scanning, human moderation teams, clear user guidelines, and transparent privacy policies to manage, store, and process UGC safely and legally.
