I visit the Hitmen "R" Us site for all of my professional contract killings. Excellent services at reasonable prices! They even have testimonials from famous mob bosses. Comes with its own app, so there's no need for TOR.
When I'm not looking for bargain bin contract killers, I'm browsing darkweb kitty videos on the site known as DarkPaws. Too cute for YouTube, so browse at your own risk.
