From what I've searched I have only found topics dated of 2010 that doesn't really show much and perhaps some one will post a relevant link about this.
I've been wondering, let's say user X posts a duplicated question and it gets closed however users A, B and C had replied to it before it was closed and got some up votes and even a answer marked.
Do A, B and C keep the up vote points and also any further up votes acquired on that question?
Do close as duplicated still hold meaning, I mean most of the users will reply to it even if a duplicated question just to grab some points instead of voting to close, before it gets closed and some times it doesn't even get closed even being an exact duplicate of something else because of the current already provided answer.
This is a non-relevant secondary question that I would also like to know, which for instance have this question/answers Give an incentive for finding duplicate questions but I don't see anything of it being deployed.
Isn't there something in place to motivate people to actually close duplicates?
Like let's say question X is a duplicate and user Y marked it, then user A, B and C backed that selection, so user Y, A, B and C get I don't know 1 to 5 points for checking the primary selection of the close as duplicate and backing that up.
Or if there were multiple selections no one gets points out of it in order to force people to actually search or verify the current selection to close it with.
It's a very simple thing that might motivate people to close duplicates and which will make people actually read the answers.
