Implement an image detection system using off the shelf projects like YOLO11 to stop spammers.
Implement perceptual hashing to generate image finger prints to blacklist or whitelist images.
I posted this on /v/'s meta thread but I'm going to repeat it here, the system would work like this.
>user posts image
>image gets tagged by the image detection system
>if with image contain certain keywords or combination of keywords, like black man and sex ,or scat the post is withhold
>then a global or local volunteer/moderator checks the post
>if its a false positive, the volunteer whitelist the image and frees the post
>is a positive, the volunteer blacklist the image and deletes the post and ban the user
This way the only people who will see the images are the moderators, board owners and volunteers.
