Don't they have a process where you can submit a government ID and have your name accepted? Honestly I don't blame the minimum wage person responsible for name screening for flagging a name that is both uncommon and one of the most common adjectives in the English language, if the policy is that fake names aren't allowed.
You mean algorithm?
My expectation is that the person who wrote the code responsible for rejecting my name in the mid-to-late 2000s was paid somewhat more than minimum wage.
Facebook is fine until you get caught in the machine at no fault and with no recourse. I would have closed my account by now but I work in low-budget theater and Facebook events and Facebook advertising are unfortunately required to make it in the industry.
