It's not currently possible to "recover" content from the dark web that is hosted on onion links. Onion links are used to access content on the Tor network, which is a network that is designed to be anonymous and untraceable. This means that it's not possible to track down the source of the content or to recover it. However, there are some tools that can be used to archive and preserve content on the Tor network, so it's possible that some content may be preserved in this way.
