There are *always* going to be hackers, scrapers, thieves, disrupters and other miscreants, from any or every country. (They have them in the offline world too, it's just easier on the net) Whatever you end up doing, go into it knowing that's a given, and build your security (and your possible responses) accordingly.
Google does respond to a lot of DMCAs, so why don't they respond to yours? I have no idea, but you better figure it out.
