Talk about Gross violation

[Acers]

A user on my site today reported a copied content violation on another site. I thought this was one more case of 1 thread copied, only to find the whole site is running on copied content of our forums.
Check my site home page: http://www.funenclave.com/

and then see this: http://www.stepheniansonline.com/forum/home.php?

^^rather an innovative style choice and use of title. I know imitation is best form of flattery but there should be some limits

It doesn't stop there. The fellow seems to be using some kind of a scraper to put our content on his site(His site and our site). I find whole forums running on stuff from our site. Ok anyway point is not to crib about that, our site is pretty big but what i wanna know is couple of things

1) I have warned the guy to stop copy pasting stuff from my site and he atm says he won't. Can anyone tell what do i do about the duplicate content created thus far. Google ain't gonna like my whole forum running on a new site copied word to word. I am worried his antics will cost us critical positions in rankings.

2) The tool he is using to copy stuff is this: (Ico Content)(https://vborg.vbsupport.ru/showthrea...ht=ico-content)
Can't a protest be lodged against that company. I don't think any forum owner allows or will allow his content to be scraped like this. And thats what the tool does do(apart from copying yahoo answers).

Any ideas on how to tackle this situation? Top it all i am terribly busy these days and didn't even notice this thing going on.
