This helps by giving a central area for finding Tor Onion sites, and is like one massive Tor linklist. If you create your own Tor Onion site, you can run it without the fear of it being shut down, due to the nature of how the system works. This allows you to host any type of content you wish without any fears, as long as you do so safely (for example, by not publicly sharing identifiable information).
