It isn't meta's fault the system is set up to incentivize this behavior, and it isn't wrong of them to do what is in their best interest. Now that we've discovered the loophole just legislate it closed. 1. make the loser pay court fees or arbitration fines 2a. the court fees grow by some percentage with each loss over the last year. lose 1, pay 1x; lose 100 pay 10x etc 2b. the court fees are proportional to the loser…
The big problem with that in the US is that many complaints that much of the rest of the world handles by having some government agency deal with them are handled in the US by the complainant having to sue in civil court.
This would discourage many people with legitimate complaints from suing unless they have an open and shut case.
