I'm struggling to understand what's creepy about this. If seeing your entire download history on that website was shocking, that's really more a measure of how much you know you've been breaking the law than anything else: there is no PII anywhere in what this service does, it just retains information about which IP (which on its own doesn't identify anyone in the slightest) was seen connected to which torrent payloa…
They flat out encourage you to spy on other people's downloaded torrents. How's that not creepy? The argument that they only display what they collected and everyone could do that doesn't change the fact that it's them that do that and they're really indiscreet with this data.
(certainly not "spy", this is literally public information that anyone connecting to torrents over DHT gets to see. And if you didn't realise torrent connection was public information, then this should be a moment of learning)
It doesn't become creepy until you can identify individuals, or groups of individuals, based on your knowledge of which IPs they use, so as much as you probably don't want to hear this: if you look up not-your-own-IP, you're engaging in creeping. Not the service.
