A couple months ago, we had a discussion about Should we be more strict about one-line answers?. The verdict was that yes, we should be enforcing stricter standards on the answers on this site. Great! That means that we can keep our quality high, and new answers have been deleted accordingly.
But... what about the old posts? There are lots of old answers that were posted before this policy was put in place that would be deleted if posted today, but since they were old, they haven't been deleted, and in some cases have gained relatively high scores.
They were posted before the policy was put in place, so they weren't eligible for deletion when they were posted... but IPS has established some stricter policies that were put in place because we saw how not having them worked. Why not go apply the fix to the problem that was decided on to what prompted the need for the fix in the first place?
Should these answers by deleted, in accordance with the new policy, or should we leave them, since they were posted before the policy was established?
As an example, here are three posts which I believe would fall into this category: How to convince people I'm not stealing their food? (+16), How to politely respond to unclear email response? (+10), How to avoid a very talkative cleaning lady? (+15)
