I mean i just joined a private tracker and so I don't have to think about it. Several, actually. It's hard for me to imagine someone taking torrenting seriously enough to set up an arr stack and not belong to a private tracker. Beyond malware, there's the rightsholder spies on the public trackers, and I'm not trying to lose my ISP over copyright strikes.

And i also truly cannot understand what your point is. Trackers are not really legal, they come and go. I don't think a few hundred or even a few thousand HN users joining across the ecosystem is going to suddenly cause them all to get raided
