This can possibly be sign of something ominous bug, causing much more duplicates.
Example of images with the same hash:
sha512_hash:ae576cb964e31d5f37ef86fecfa3e33a8b6246a0eb509601b374a867e1f210967f30fcfbc89fb8054437972e0d724121f289d6488a608deec4c3d6417749df43
id:1559153 OR id:2593714
I have created duplicate report, so this specific example could possibly disappear. But if this happens a few times, it can be happen a thousands times more
