Here is the post:
Why did Krishna steal butter and milk?. This nearly 2 years old answer is deleted under no clear written policy.
I have presented 2 reasons to the Qn & also cited following in my answer's last para:
Since this question is about the reasoning and hence it cannot cite any accurate reference. However, above 2 reasons can be clearly seen in 2 of the tele-episodes of BR Chopra's Mahabharata which closely followed "Gita press, Gorakhpur" as its base source.
Now here are my defending points (also excerpts from discussion with Mods):
- We didn't have any solid meta policy for deletion based on type of sources when this answer was written.
- The tele serial was well respected & it followed "Gita press, Gorakhpur", which was presented in writing.
- The accepted answer which is older than mine also doesn't cite any sources; However Back it up policy existed even before that answer. But that answer is not deleted. (No policy on date criteria for deletion).
- There are many old & new answers w.r.t. this answers which don't cite sources; That's why we call it targeted deletion
- Lastly, such Qn-s which ask for "Why happened" would mostly generate opinion based answers. Because scriptures mostly describe "What happened". In fact many times, "Why" Qn-s cannot have sources. They would generate slightly opinion based answer & official policy for opined answers is set by Mods in this post:
What should we do about opinion based answers?
Update: As per discussion with a Mod in comments below, the grandfathering policy or whether to delete all the unsourced answers -- is under discussion. This discussion is happening as early as this post: Let's delete all old answers from early days of the site that lack any references at all, if not before. However my answer was deleted as recently as 19-Apr-2017. That means it's deleted after the discussion initiated. Which is not right. Hence answer should be restored to its undeleted state until the policy is finalized. That's more practical compared to deleting all the unsourced answers.
Update 2: As it seems that the discussion with the Mods are failing on the fairness of the deletion. To avoid dragging this issue further, I have decided to add "some scripture", which is related. Though for this Qn absolutely no sources can be cited IMO.
