Hello World,

today, @[email protected] has provided an update to the media upload scanner we’re using. This should reduce the amount of false positives blocked from being uploaded. We have deployed the updated version now.

While we do not have stats about false positives from before we implemented the scan when uploading, those changes did not change the overall data availability for us. Flagged images were still deleted, they were just still served by our cache in many cases. By moving this to the upload process, it has become much more effective, as previously images could persist in Cloudflare’s cache for extended periods of time, while now they won’t get cached in the first place.

Over the last week, we’ve seen a rate of roughly 6.7% uploads rejected out of around 3,000 total uploads. We’ll be able to compare numbers in a week to confirm that this has indeed improved the false positive rate.
