At the moment I have a growing problem with robot registrations in the catalog. Right now I use a simple “captcha” question asking which color a banana has, but of course every AI can answer that easily. Before that I asked for well-known banana brands, which AI also knew without problems.

Does anyone have an idea for a question that a real banana label collector would know, but that cannot easily be looked up or answered by AI? Maybe something very typical from the collecting scene or a trick question that only makes sense to collectors?

I would really appreciate your ideas.
