Ask HN: Does asking “Why am I being downvoted” get upvotes?

In Hacker News (and reddit) when a comment is edited that says something like "Why am I being downvoted?" or "I don't usually say this, but why the downvotes?" do people then tend to upvote these more than if they had not been edited?

As an aside, I think there may be two reasons why people edit the post but which are hard to determine externally:

1) "I don't understand why this is being downvoted" they may be saying "I DO understand why this is being downvoted but I think I should have support". It's an appeal for justice, an equalling out.

2) "I don't understand why this is being downvoted" and they actually don't understand why. They are either asking for information to help them understand, or they are admitting they are blinkered in their views and cannot understand why there is opposition. By editing the comment they are appealing for others to back them up.

Another reason could be that they are new users and are unfamiliar with how the platform works, how karma and voting works etc. By asking "why the downvotes" they are saying they do not understand how voting works. Possibly they are comparing the mechanic with Facebook "likes".

Regardless of the reasons for editing a comment such, I think it is a beneficial activity as I believe that by doing so it encourages others to upvote. Is it actually true though? Have you edited your comment in such a way, why? Did it work for you?
