It is not acceptable to post an answer that is entirely someone else’s words. It is fine to research an answer, but proper research means using several sources (not just one) and putting all the information together by re-writing or re-wording.
If you find an answer that has been copied entirely from another source you should moderate it and mark it as: Been Copied (plagiarism).
