Quite recently I saw a few posts of new users of this site (which were just joining MSE) which were on a very basic level and indeed contained some mistakes or even basic mathematical misunderstandings.
I tried to figure out what the problem was and tried to provide enough basic information in my answers to clear things up a bit. Additionally, I edited the questions regarding the formatting (Latex etc), which one obviously cannot expect from a user who just registered to MSE, and after I finished, I even edited the content to make clearer what the asker wanted to know — I just tried my best to shape these questions into some worth staying on MSE.
But while I did this, the question got voted down quite fast.
This got me actually a bit upset, because after the discussion and editing the Q&A was not at a state that would have deserved these votes, and it feels like there were just some people looking at the question in its first state saying “this is basic rubbish, how can one not get this basic stuff!”, but not even bothering to leave a comment or even editing the question. But because of the downvotes, it seems that my attempt to improve this question would've been completely useless. But as I perceived especially on some meta discussions, new user's posts are generally not disliked, especially as this is not MO.
So my question: Is there any possibility to notify downvoters that someone edited the question or something similiar to make them rethink their vote? Or generally — how would you handle such situations? What could I do better to prevent such downvoting?
