Because it doesn't, it lets you look at what other IPs have been doing. (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.
