prevent users from uploading the same picture over and over again
Store fingerprints for the pictures uploaded and prevent users from uploading the same pic over and over again. This would benefit in three ways:
- Pic stealers would automatically be blocked from using stolen pics
- Serial account delete/recreate cycles might be reduced
- Serial photo delete/repost cycles might be reduced
While minor changes to the pic could get it to bypass the fingerprint check it at least makes this a more and more laborious process and would perhaps get them to stop.
