be aware of sites like this, and that torrent activity is easy to amass data on
I want people to understand how these things work and to be aware that everything on the internet is public. finally understand that all this data collection can be done entirely by an individual, public actor without any necessary special sums of money or influence or power.
It says they scrape torrent sites, but I would bet most of their data comes from trolling the DHT. If your torrent client supports turning DHT off, that might keep you off their radar.
