@starball Thanks for the suggestion. We generally don't close questions as duplicates unless they're essentially asking the same thing, or the community decided on Meta that there should be a general community wiki to handle them. In this case, although these questions are all related to duplicate content, they're asking about different things related to that.

We do have a community wiki about what duplicate content is, but it's for very general questions so the community doesn't keep providing different answers to that. More specific questions wouldn't be marked as a duplicate of that however.

@dan alrighty. thanks for taking a careful look!
