Start with TL and MAM and work your way up there. MAM has an invites section for example, you can get into lots of other good trackers like Aither, PixelCove, OPS, ANT/NBL, BBT, etc if you meet the invite requirements listed in each of the invite threads.
Generally this is why you want to have multiple providers - one that follows DMCA and one that follows NTD. That way, you have a higher chance of actually finding the content you want before it gets taken down.
Not too surprising but still disappointing regardless. Self-hosting is the only way to go for this.
