Is There Anything I Can Do To Get A Revenge Porn Website Taken Down?

I’ve been battling with a revenge porn website for the last few months. I’m a male, and haven’t had anything leaked there, but it’s absolutely vile. Everyone on the website is clearly posting revenge porn, creepshots, and even CP. I’ve reported it to the FBI twice and it’s still not taken down. I think it may be a lost cause because they have rules against posting this stuff, but they often don’t care or only remove the most extreme stuff. Is there anyway I can get this website removed? I saw something about ISP’s being able to block websites. What steps can I take to ensure the best possibility for this site to be taken down?
