Downvoting valid answers

[Santhosh Kumar Jayaraman]

recently i have noticed someone is continously downvoting my answers even when my answers are correct and without any valid reasons. Today it happened again. Continuously someone downvoted 9 answers of mine in 2 minutes. I guess its a single person did. can you check whether its spam or someone is doing wantedly?? Its looking odd that someone is downvoting even accepted answer and upvoted answers by other. I have posted my image http://www.freeimagehosting.net/k9r9b\[^\] it looks like the user have targeted me particularly. please check.

I can understand that this may be frustrating, but please, do not cross-post. I'm sure that there will be somebody looking into the issue, as it definitely sounds like abuse to me.
