Our answer quality guidelines lead with this text:
What is expected of an answer on this site?
An answer needs to be tailored to the question. Answers that consist solely of a product name or link and generic information copied from the product description or other promotional material may be summarily deleted.
In another meta thread, I proposed a policy which hasn't met any opposition:
Answers must be tailored to the question. Any answer that consists solely of generic elements shall be summarily deleted.
So if you see an answer that consists solely of generic elements, please:
- Comment on the answer, pointing to these meta threads, and suggesting how the answer could be improved.
Although comment notifications are removed from the inbox when the answer they're on is deleted, answerers can browse comments if they are alerted to the answer's deletion. Moderators can leave a comment before deleting the answer, and moderators' comments remain in the inbox.
- Flag the answer, either as a canned “very low quality” flag (for community review) or as a custom moderator flag (for moderator review).
Note that personal experience, while appreciated, is not strictly required. What matters in the end is not if the recommended product was good for the answerer but whether it is good for the asker. What matters is that the answer addresses the specific needs expressed by the question.
