Getting a few downvotes does not mean serial downvoting.
Your question has 7 downvotes and 3 upvotes (at the time I'm writing this).
One person cannot downvote more than once on a question. So it is not serial downvoting. The downvotes came from different people.
As for your answers, they have 1 downvote each. Again not serial.
Anyway, I've looked into this ...
No. You cannot trace upvote/downvotes since it happens anonymously. Even our moderators cannot see this information, I believe.
I think this is intentionally put in that way in order to avoid further problems. If we came to know who are the people who downvoted our question or answers, then there is a natural tendancy of "revenge". Similary if we came to ...
The answer element in the dom has the class downvoted-answer. I don't know exactly what the downvote limit is in order to get this class, but you can try to check if it's -3, by upvoting it (to get it to -2), refresh the page to see if it's still greyed out then retract your upvote.

And for your another question who gave downvote on your post , I think stackexchange core team can see that, I doubt if ...
Don want to post as comment ....
Marius is right in general, but it looks definitly wrong to me - unnormal voting.
Every day day there are poor, but upvoted questions. Same for not downvoted oneliners. This is a really well explained question, that got -10 so far.
Seems not correct to me, since it doesn't fit to other voting behavoir.
Maybe just "groug ...
Well... these are the rules. Read this to see how reputation works.
Also this post explains a bit why you get -1 rep when you downvote.
-2 to post owner
-1 to you
This is done to make sure downvotes are cast only when you feel
strongly that something is incorrect / wrong / dangerous / of low
And here is an other explanation:
For this problem I think you can do down voting if you want to do so ,
you can not force someone to provide full detail answer because here question also asked by that person.
in this kind of case you can leave comment to OP that provide full answer but if he/she don't want to answer you can not do more except flag that post as low quality Post, if ...
Question: Is there anything which will prevent negative vote on possible answer?
Here are my suggestions:
First check question description is clear
Use comment's to clarify even question better
Don't tried to answer quickly unless you are 100% sure
At the end answer the question and let the community decide what they think about your answer. ...
