Along those lines, how do they verify that what is being downloaded is actually the real thing.
For example, what if I created 300 txt files of popular music songs, had them named artist - song title . mp3, and made them about the right size.
But, in reality, they would not be what the file says they are. As I said, I would start with a text file, make it the right size, and rename it to .mp3.
If I was to do that, and host them, and people started to download them, would I get "flagged" as hosting "copyrighted material", when the files themselves was bogus?
Possibly yes. if the hash happened to be close enough to the database I bet the automatic system would fire off a DMCA notice to your ISP.
the DMCA has zero human oversight. Which is why false positives happen. NASA had part of a news conference on Livestream cut off once. They showed video of the curiosity landing and that triggered an automatic copyright system(because some news source also had that same video.)
