I observed a user accused of plagiarism a few minutes ago for quoting copied text from the Internet without citing the source. Now here's my question: Is quoting not enough proof that the Op never intended to pass off someone else's work as his own? Please educate me.
Personally, I think it is plagiarism, because you really need to give credit for what you are quoting. But I understand this might be polemic and not everyone agrees.
Imagine you spotted a helpful tip on an image and thought, "Oh, I saw a question on the forum, and this material is the ideal response to the topic," and instead of claiming it, you copied it and put it in a quote since you didn't know the original link? I'm not saying this is what the OP did because I'm not in his head but c'mon the copied content was helpful, now how do we classify such a case?
