Nope, your lucky no litigation was involved (You do need to be a certain size before that becomes a problem though). Streaming sites have been getting sued left and right for the last 2-3 years. It does not matter that you dont host the content yourself.
I would pull down the offending links and call it a day. Better than killing the entire site, right? The next place they go is going to be your host.
In theory the only way to get away with what your doing (long term) is to run everything offshore with fake info, probably via BTC, at that point you can just ignore take-down requests. Not much you can do about google nixing a page though - other than replacing the offending links with mirrors.
I'd look into aff-programs that pay via BTC as well - in many cases when they cant ascertain someones real identity they go after your advertisers, and get you that way.
