You won’t find a full-fledged replacement for thenewpiratebay, so don’t even bother looking. Maybe something similar in meaning, but not in content. I agree that it’s not the safest service, but you won’t find content like it anywhere else. So just install a good antivirus and WAPN. That and the mirror sites will give you a lot of access. But that’s my decision, and you decide for yourself.
