1. You receive a takedown notice
2. If it’s not valid, you submit a declaration that it’s not
3. Your content is restored and the claimant now has to take you to court if they still think it’s infringing
4. If you lied on your counterclaim, your now also guilty of perjury
The only thing it’s really missing is an imminent threat of perjury for frivolous claims (there also some obvious areas to make the process more efficient). But as far as a simple way of managing offending content, while still providing due process, the general format is quite good. It’s other unrelated policies that tend to get people the most riled up.
