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