This seems unprofessional
It is.
But then again, did you pay 100 $ up front to publish here? Were you asked to show your real life ID to proof you are who you claim you are?
You have a patreon. What did they ask from you, before approving your account? And why do you not link from your patreon to your Itch? Anyone crosschecking if you are who you claim you are, will not find such a link. Maybe you are some scammer impersonating the real spicy pixels ;-)
Unfortunately, Itch's services get abused every day, so they do have automatics to look out for anything that might need human staff attention. And unfortunately, that staff seems understaffed and that automatic gives false positives. We do not see the correct positives.
