Serial downvotes in quick succession on all my posts

Suddenly, someone downvoted all my posts.
Why would someone do this and isn't there some feature to stop this?

I think it may be due to my last activity (commenting on a poor question); all I did was offer advice.

Obviously it is an immature Stack Overflow member. Is there anything I can do to reinstate the reputation? I am not too fussed; if not, I just think it is a bit stupid.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Yep, all I did was try and be nice :( – rickyduck Sep 9 '11 at 16:42
In this particular case, there was also a sock puppet helping to downvote. I've merged and suspended; if you recalc now, you might get some if not all of the points back. – mmyers Sep 9 '11 at 16:42
It seems we both got hit byt he same guy.... u were nice. doesnt mean he will be.... – amanaP lanaC A nalP A naM A Sep 9 '11 at 16:43
@mmyers -- I was hit by the same puppet - also some of the other closers of that question. – amanaP lanaC A nalP A naM A Sep 9 '11 at 16:44
@mmyers ! ha ! that was the same user i complained about a few months ago? wow.... – amanaP lanaC A nalP A naM A Sep 9 '11 at 16:45
@Neal - ErrorErrorError is the deleted name – rickyduck Sep 9 '11 at 16:46
@rickyDuck -- it is the same user that i complained about in july:… – amanaP lanaC A nalP A naM A Sep 9 '11 at 16:46
@Neal - I mean, ErrorErrorError wasn't his name, when he got deleted it was replaced with that – rickyduck Sep 9 '11 at 16:47
I know, he was known in july for making many many account. see my question. – amanaP lanaC A nalP A naM A Sep 9 '11 at 16:48

Why would someone do this?

Because people are inherently naughty, all good acts just cover up the fact.

Isn't there some feature to stop this?

Why, yes there is. But not so much prevention as it is detection. Down-voting can't be deemed as a serial case on a per down-vote basis - the system will analyse the voting "habits", should recognise the pattern and correct your "karma".

EDIT: Alternatively: come here, complain, get the satisfaction of seeing the user boxed off, evidently.

If there is a 24 hour "Fraud Detection", why not on an as is basis? – rickyduck Sep 9 '11 at 16:41
If there is a 24h "Fraud Detection", then why waste resources running it per vote? It's not like you've lost your wallet for the day and can't buy foodstuffs. – Grant Thomas Sep 9 '11 at 16:43
What resources would it though? However I guess if it was more efficient, SO would implement it – rickyduck Sep 9 '11 at 16:45
I don't know exactly what resources, but suffice to say that when a system which normally "does stuff" does "more stuff" then it'll use more "fuel"; in this case we could even consider clock cycles. – Grant Thomas Sep 9 '11 at 16:52
For reasons that really should be obvious, no one's going to give you the exact details of the fraud detection algorithm @ricky. Think of it like writing a cheque - it may take up to three days to clear, but you should consider the money gone immediately. – Shog9 Sep 9 '11 at 16:52
Fair enough, points taken. – rickyduck Sep 9 '11 at 16:53
I remember when I was once serial-downvoted and my immediate thought was, "Really? Is this all this person can do to me for retaliation? Man, Stack Overflow is great. Anywhere else on the internet this would have degraded into a flame war from which there is no escape." – David Sep 9 '11 at 16:56
why isn't fraud detection included in recalc? – genesis Sep 9 '11 at 17:16
@genesis Analyzing every vote you've gotten is more complex than simply summing them up to get a score. – Matthew Read Sep 9 '11 at 17:26
@MatthewRead: So separate link to "remove downvotes given by maniacs" ? – genesis Sep 9 '11 at 17:27
