Q:

Why am I getting downvoted when I downvote someone

Possible Duplicate:
How does “Reputation” work? 

I downvoted an answer to a question and I got downvoted myself. Could somebody explain please?

A:

You are not getting downvoted. 
When you downvote an answer, you lose one reputation point. This is explained in the FAQ.

A:

The reputation loss is because you downvoted, not because you were downvoted.
See the docs for more information.
