If you've got no money for litigation, then my suggestions are:
Lesson Teaching Option:
If they are a big host and this appears to be part of their business model then perhaps you can do a little research, find other people affected (preferably US based) and get together for a class action or at the very least gain the interest of lawyers who see the public interested angle and will work pro bono, or no-win-no-fee.
Getting Content Taken Down Option:
As a host, they will have a network provider, someone who assigns them their IP addresses and network access. Go to
Domain Tools, search their domain, click on 'Server Stats' tab and see who provides their IP address. Send your DMCA to the network provider's abuse address and you should see the content disappear pretty quick sharp.
Other Option:
Send a DMCA to Google and other search engines to have the content removed from all search listings.
But First:
Send a polite but firm email to the host's abuse address and demand they take down the content within the next 48 hours. List the URL of the offending page, and state you are the copyright holder etc (do a search for a good letter template). Tell them that if they don't comply you'll be contacting their network provider (list their details so they know you are not bluffing).
