Back in the early days of the site, we decided that we didn't really care much for copy-paste answers, and especially not for plagiarism. They are, at best, half a step up from a link-only answer, and in many cases only tangentially answer the actual question asked. At worst, they run a high risk of copyright violation.
The current practice is to downvote posts which comprise little more than copy-paste from elsewhere, and to delete plagiarism on sight.
Despite this, copy-paste answers continue to not only be posted, but often get upvoted by the community without sufficient downvotes to counter them (purely from a reputation perspective, it takes five downvotes to counter a single upvote): this not only gives users the mistaken impression that such posts are welcome, but that they are in fact encouraged.
Over the last two days, I spent hours deleting blatant plagiarism from a variety of users; in many cases these were relatively new users whose posts were heavily upvoted. As many of these contained absolutely no downvotes, and no comments to the contrary, it is not surprising that these users considered this sort of behaviour acceptable.
This is not the impression we want to give, and it remains highly unlikely that a site with large swaths of copy-paste will ever become the sort of site which will attract actual experts. In my own (limited) experience, forums which are full of such are not the forums which are frequented by scholars.
Now that we've had a good…year and a half?…of actual site experience under our belt, I feel that a review of our current practices would not be amiss.
Is our current policy on plagiarism and/or copy-paste sufficient? Do we need to reconsider and/or modify it? Basically, I feel we need a discussion on the copy-paste issue and what, if anything, we should be doing (different or same) to deal with it.
