How to generate and manage a lot of tor address(mirrors for users) in a tor site.
Just like drughub is doing.
/u/drughub can you help here.
They are pre-generated, pre-signed and activated/removed as needed. While I can't get into specifics I can tell you that you need to get familiar with Tor control port and to have decent infrastructure, depending on how many onions you have active at a given time.
