I wish I could post a screenshot here, because you are wrong.
Try going to a public library, and access your links WITHOUT logging into any Patreon account or having any Patreon cookie on that computer.
You can add a screenshot to your post on Itch. Do you mean this message? It's an age verifier and you don't need to actually make an account to confirm it.
I've tested it out years ago, and it works from EU regions. Can't say for your region. I can only theorize that Patreon may have additional checks for some Middle East countries or something like that.
