Is the arbitrage opportunity worth it? It doesn't seem like it is considering the limiting factor being the court system, and you can't really arbitrage off cheaply off miniscule enough violations to profit more than a few one off cases. Damages must also be present, so maybe a service to service offering where one party disparages you online and then you take Meta to court for not suspending that party would work, but thats fraud, and if found out you risk quite a bit for sums that seem to not really exceed more than $15,000 across the US (from the article).

Pity the people who are not U.S. citizens. Meta is the worst.
