For a few decades the touted solution to mysteries like these was
   decentralised and cryptographic peer-to-peer alternatives.
   This is still a very valuable solution, but it does hold a big problem:
   the efforts are persistently disrupted, such that development and
   usership stagnates.
   One imagineable interim alternative might be working directly with
   human service providers.
   If I were personal friends with [1]meetup.com workers associated with
   delivery of my search results, they would be happy to help me ensure
   the results match the planned events.
   Similarly, if I were personal friends with [2]google.com's network
   admins, they would be happy to ensure that I got the real front page.
   Overall, this is a situation that has been developing for many years
   now.
