Moderation Team goals is to build and manage the moderation process.
Moderation Team is composed of experienced users, or people motivated to help (and who are not afraid to ask questions).
Moderation rules
First of all, as a moderator, if you're not sure of what you're doing, ask other moderators in the #moderators chanel on Slack.
For every case you should take care of the whole concerned product: a moderation issue often reveals a completely false product.
If you're not sure a new product matches with a real product, delete the whole product.
The following rules don't apply to the product itself: ex. if a product contains a picture with a face.
1. Product picture with a people face
The face is clearly recognizable? => Delete the picture.
The face isn't clearly recognizable? => Keep the picture, optionally crop it.
2. Product picture containing both the product and part of a body
The part of the body can re-identify somebody? => Delete the picture.
The part of the body cannot re-identify somebody (ex. legs) => Keep the picture, optionally crop it.
3. Product picture only shows something not related to a product
Delete the picture.
4. Product picture containing parts with obscene or illegal content
Delete the picture.
5. Empty or nearly empty products
When the product entered is almost empty (no name, no picture, no nutritional information, but possibly lang and country), it is automatically deleted. There is no need to delete it.
When the product only have very few data (name, country, maybe brand) but no picture, no or very few nutritional information, it won't be automatically deleted, so you can remove it.
6. Non-food products
Many non-food products are published on the Open Food Facts website.
If possible, move the whole product: just put obf or opf or opff (respectively for Open Beauty Facts, Open Products Facts and Open Pet Food Facts), in the first field of the form, introduced by If the barcode is not correct, please correct it here:.
Sometimes the product already exists and you can't move it. In this case:
Screenshot to understand how to move images.You can still move the photo using the Manage Images interface (see screenshot). Select the photos and fill the Barcode field, either with obf or opf or opff.
When you have moved the photos and the content, you can delete the product on Open Food Facts.
7. Picture taken from manufacturer's site, shopping sites or other sites
Can I add product pictures or data from the manufacturer's site, shopping sites or other sites?
Probably not. Almost all other sites forbid reproduction and reuse of their data and images, and that is actually the reason why we have created Open Food Facts: to make all this data available to all and for all uses.
To avoid any legal problem, we therefore ask contributors to only add pictures that they took themselves, and only data that is coming from the product packaging and label.
Hence, if you find a picture that is taken from other website:
check that it was not uploaded by the producer itself
make sure that it is taken from other website by finding the original picture. You can use reversed image searches. Mind the details such as expiry date, lot number, etc.
ask confirmation from other moderators
make sure that all possible information from the picture have been extracted to the fields (such as product name, brand, weight, etc.) because if this picture is the single picture of the product, these information will be lost.
finally, delete them

Recurrent vandalism from a user
Here is our current process about it.
Don't delete the user account: it's easier to watch the activity of a known vandal.
Try to contact the user to stop him/her.
Write a factual email (see template below). Be gentle! We are a project for providing food transparency and not to argue with somebody about bad practices or legal issues.
Tell other moderators about your action.
Prefer moderation-off-private private Slack channel. Other channels are ok.
If you don't get any answer and the user still abusing, block his/her IP.
Ask a sysadmin to block the IP.
Sysadmin can find the corresponding IP: sysadmin@off1:~$ [todo]
Sysadmin should add the date to know when to delete old entries.

FAQ
Why does Open Food Facts Keep All Images, Even Old and Duplicates?
Open Food Facts keeps all product images, even old and duplicate ones, for a few key reasons:
- Data Verification: Images act as a primary source of truth for the information entered. By having the actual packaging alongside the listed ingredients, nutrition facts, etc., users can verify the data’s accuracy and even spot errors.
- Some images include information not visible on similar images
- Sometimes, we realize the value of information many years after they are taken, as our knowledge of little symbols evolves, or as data extraction systems become better.
- Tracking Packaging Changes: Over time, product packaging can change. Keeping older images allows users to track these design modifications and identify specific product versions.
- Open Data Philosophy: Open Food Facts is committed to open data, meaning information is freely available for anyone to use. This includes all images, even duplicates, which can be valuable for various purposes. For instance, researchers might use them to analyze historical food labeling trends.
While storing duplicates might seem redundant, the benefits of comprehensiveness and data verification outweigh the storage space considerations for Open Food Facts.
