Google Drive flags files for copyright infringement due to digit combinations

"...she uploaded a file named "output04.txt" that consisted of a single character, the numeral one ...

Shortly after uploading them, I received a string of emails from Google indicating that those files had been flagged for copyright infringement...

the automated email notification she received offered no way to push back against the determination of Google's content vetting algorithm – the Request a Review button was not included in the message she received ...

The e-mail explicitly said 'A review cannot be requested for this restriction,'"

How far does pattern this need to go, before someone changes direction?

For perspective, Apple was scanning iphones for allegedly illegal files, based on their hashsum. However, I'm not sure the database of illegal hashsums is publicly available?

Presumably Google is doing the same thing, but in the cloud. However, does anybody have access to the database of copyrighted hashsums?

If society is going towards a world where we blanket filter based on the file's hashsum, then perhaps the government entity overseeing copyright should have a public database of these hashsum's? That way the public can know things are, or not, prior-art? Not only prior art, but potentially illegal in other ways.
