I'm completely in favor of everyone suing facebook for literally any reason, but to be clear, what would the legal standing/basis be for this small claims court?
Beyond that, the point is just to make them notice you, so anything might be good enough. Reporting to a regulator like the CFPB can also be effective if the case looks financey - I got my PayPal account back recently that way after they didn't like how I typed in a tracking number and banned me for life.
