If the few blokes using this scam their way into few hundred terabytes of free storage, so be it, it's not worth the hassle for Google, imo.
edit: Apparently an account can create up to 250 docs a day https://developers.google.com/apps-script/guides/services/qu...
This. They probably thought of this exact scenario before adding unlimited docs. They probably even expected somebody to make a script for it. Hell, a few of them might even have a script.
As long as a lot of people don't start abusing it or make a file-sharing service based on it, then they probably won't care. Basically, not until it's a significant enough threat to their bottom line.
Ultimately, it's no different than the inevitable person that just has a script to generate garbage and upload it to Google Docs as fast as possible. That's what the 250 docs a day limit is there for.
The README.md says that UDS can store ~710kb per doc.

TBH this is not unlike reporting a security bug to a company as a white hat, but more like a grey hat here.
