Archive operators must constantly write scripts and employ automated filters to scrub illegal content from their databases to avoid being shut down by hosting providers or law enforcement. Conclusion

Some advanced archives integrate reverse image search technology. If you do not have the exact file but have a similar image, the search tool analyzes the visual patterns, colors, and shapes. It then matches your image against millions of stored graphics in the database to find original threads. Why People Use 4chan Archives
