DMCA doesn’t give the service provider much room to adjudicate these claims. The intended way to correct bogus DMCA notices is a counter notice. GitHub’s particular policy says they reinstate content 10-14 days after getting a counter notice, unless the claimant gets a restraining order: https://docs.github.com/en/free-pro-team@latest/github/site-...
One of the earlier worries about the DMCA takedown process was that it would be used fraudulently to take down important things right before an election, or during a breaking news window to bury a story. I wonder if anyone has tried that yet.
