Images are checked manually, not by the bot. Finding the users who share just the picture and marking cheetah to double check the post helps in that. Most of the image abusers are not spending too much time to write the posts.

In the community that I manage, all the photos are checked manually. Ideal situation would include that this verification is made in every community but many admins does not even know how to do it or use copyrighted pictures on their own as well... Education is crucial and we are trying to do it constantly.
