Based on an article I found from 2015 on MD5, it takes about $0.65 in compute and 10-12 hours to make small mods to an image to achieve an arbitrary hash. I dont know this hash used here, but would it be reasonable to create a 'make small changes to this image until it has this hash value'? If so, there will be false positives but they will be intentional. Black hat can send a collection of 100 modified but innocent meme images with nefarious hashes.
