If there's enough people who were wrongfully banned for any reason on Facebook because their review process is broken, maybe it's time for a class action suit?

If there's enough people who were wrongfully banned for any reason on Facebook because their review process is broken, maybe it's time for a class action suit? Also, banning somebody and not keeping the relevant evidence, not showing the evidence to the client so that they can archive the case themselves to appeal in court? You don't have any anti-discrimination laws to prevent sellers choose their customers on subjective basis? Because at this point Facebook cannot prove that the people violated the ToS and thus Facebook is restricting the services it offers to then.
