Especially hard to get the courts involved if the claimants are in other countries.

About the best you could hope for is if a person can be shown to be acting in bad faith they could have all of their takedowns reversed and the material in question flagged so that further takedown notices trigger an audit. In practice this might just mean making a new account for each takedown notice, but it does raise the bar a bit on bad behavior.

I'd also assume big media cartels would be exempt because operating in bad faith is their entire business plan and they're willing to sue to maintain the status quo.
