Various sites on the Stack Exchange network take questions of the form "please identify this thing", perhaps from a photo or a description (where the nature of the "thing" would depend on the individual site in question). Some site scopes place strong restrictions on such questions or disallow them altogether. I've seen and participated in debates on various site metas, where some people claim that "many" or "most" sites disallow them while others claim that "many" or "most" sites allow them. Let's collate the facts and find out for sure.
Which SE sites accept identification questions?
