There are no such rules about it, so I think bitcoinermatt will getaway with it very easily which is sad of course.
If admins confirm that's the official stance on cases like this, so be it. I just wanted clarification because report is still unhandled, and I don't waste my own and admins time reporting if I stumble upon similar case in the future.
In my opinion it should be treated as plagiarism in its worst form.
With this kind of mindset, nothing positive can be expected from such a member.
