What if FC (the app, not the protocol) decided to close new user onboarding indefinitely, active immediately? Like a hard cap on currency, but instead on community, not to mitigate monetary inflation, but quality dilution. 

Given that assumption, if you are FC team, what’s next?

A potential solution would be to build an app on top of the protocol with some algo that prunes your network every x months based on “quality” or lack thereof. The harder part would be determining value of each person within your network.
