I suspect the only solution for these cases is some form of small claims court / independent arbitration process (and not just for Meta, but for all of the FAANG bunch and their like). Can you imagine a big tech employee having to say to a judicial person, "The system automatically blocked the user, then automatically denied their appeal, and we have no way to know why, because there is no evidence or other supporting data because we deleted it all." Surely any form of arbitration or legal scrutiny would turn that into an instant default judgement against the tech giant? And while I would generally support the right of any business to choose who to do business with, there comes a point when a business becomes somewhat monopolistic, and a gatekeeper of access to the market, at which point these kinds of decisions need to have a reasonable route of appeal. It remains to be seen if the behaviour of these companies will change in response to legislation, for example the EU Digital Markets Act has some obligations relating to "Allowing business users to access end users" that may be relevant.
