I found this older question on Meta that asked about duplicate answers that were posted simultaneously. This question, however, is about answers like this one that are posted on old questions, with content very similar to that of other answers but too general to be considered plagiarized. Let us look at this answer here.
You 'satiate' your hunger. A more definite way of saying 'satisfy'. 'Satisfy' seems too vague
Satiate is used in several other answers, and the notion that "'satisfy' seems too vague" is already implied in answers that don't in fact suggest the use of satisfy as a first choice (all but one answer).
Should we downvote such answers on the ground that they don't contribute anything new (and to discourage people from posting answers that others have already posted in order to increase their reputation)?
