Without source and without quote brackets, it is plagiarism.
With source and without quote brackets: it is not a plagiarism.
Without source and with quote brackets: it is surely not a plagiarism.
You're quoting the "plagiarism and cultural differences" thread and I'd kindly suggest to read the thread all the way to the end. The fact that the OP has been merited, doesn't mean it's correct.
No intent, no offence. The cultural aspect is completely irrelevant.
Contrary to popular belief, the plagiarism rule and application thereof is very lenient. It's usually fine as long as moderators can see that the user didn't intend to pass the text as their own.
^As usual, suchmoon summarizes the whole thing perfectly. I'd however would like to add that the application is imho completely just and correct.
There's simply so many plagiarism claims which are completely unjustified, that it seems as if the mods are lenient. They're not lenient, they're right. (or, in some cases, impossible to prove)
I'm not quite sure why this is so difficult to understand for some users, and I'm really amazed about how many times this has been repeated already and yet people refuse to understand this very simple rule.
