Few minutes ago someone downvoted all my question and answers in stackoverflow.com.

My reputation today

As you can see in the picture:

It's unethical, drops my reputation and my tags points..

I would like to know who did it, why and how to revert this?

I appreciate.

EDIT

I didn't know about the meta sites, I already created one account for me and will post properly in the next time I have a similar situation. I kind of freaked out and made things hurried. I posted in the wrong place I know, don't need to downvote this question anymore.. This situation is done. Thanks.
