So you may have noticed that recently uploads were changed to only be available to logged in users. This was due to some bad actors uploading CP w/o accounts and abusing our good will.
Since then, we have gotten assistance from the Dutch hotline against child sexual abuse (https://www.meldpunt-kinderporno.nl/) in the way of having access to their hash checking service API. (https://www.meldpunt-kinderporno.nl/over-ons/hash-database/) This allows us to compare the hashes of uploads to their database to detect child pornography at the time of upload.
This does not change the fact that we record no IP information. The only data being sent to their server is the SHA1 hash of the file uploaded. If a detection is made, no additional information is logged, just the file is not processed.
If you have any questions feel free to send me an email or use the contact page.
