Not sure where you're at with it. But technically you can issue a DMCA letter to his hosting company. Lots of places to look up hosting company from URL.
And usually they don't want hassle and will take it down.
Here's a link to sample letter:

Personally I think DMCA is overboard, but it's your content. Do with it what you'd like.
