Recently, a moderator deleted two low quality answers. The explanation given does a good job of explaining why:
We're looking for long answers that provide some explanation and context. Don't just give a one-line answer; explain why your answer is right, ideally with citations. Answers that don't include explanations may be removed.
This site has a lot of these types of answers cluttering up the site: answers that don't really provide an explanation for why their claims and conclusions are correct. These answers don't really have much, if any redeeming value. Despite this, these answers sometimes attract upvotes, particularly answers posted during the private beta.
Similar to how we have a process for closing questions, would it be useful to have a process for deleting unexplained answers. One potential process could be that answers flagged using a custom flag would be reviewed by moderators, who, if they agree, would apply a post notice to answers, and delete after a specified time period. Disagreements about when to apply this process could, like disagreements over close votes, be taken to meta.
Here are the two deleted answers if you don't have the points to see deleted answers:
I think it means, next time he will be given a long jail sentence, and the judge won't be foolish enough to give him a short sentence or exhibit any clemency.
I think (correct me if I'm wrong, I haven't read it yet) he means that next time he won't hesitate next time or foolishly give mercy.
Here's another example of an answer that a moderator put a post notice on but didn't delete:
It means a man must give up all of his self-importance and pride in order to be a servant of God, that as long as he (emotionally) hangs on to what he was before finding God, God cannot (or will not) transform him into what he should be with God. It is a demand for surrendering yourself to God's will completely without reservations as to what God may do with you.
