Banned image hashes?

Hi!

So I know we can ban a user, close accounts, or could ban the IP of the user at the OS level.

My problem is that other individuals may want to upload the same copyrighted, illegal images over and over.

A way that this is dealt with in other user-uploaded sites is comparing the file content or more specifically the hash (md5 hash for example) against a known database of banned material.

Is this too much of a performance hit to implement?

This helps prevent reoccurring abuse over and over by the same content. Now granted they could just crop the image slightly and the md5 hash would be different....but trying to think of a way to prevent reoccurring abuse.

Thanks!

They only need to change one pixel to make the md5 totally different so in the practice use md5 to avoid the recurrent upload of this kind of content is not something that it will help you a lot. In the other hand you could ban all the IPs or even the IP range and that will surely do more for you.

IP bans is something that it will be added but banned hashes don't take that much my attention.
 
I will add this just to get rid of those Windows default images that gets uploaded everyday to the demo.
