> People may say that Discord and similar will compensate, greatly, as the number of interactions can grow a lot. Are Discord discussions indexed by any public search engines? What about communities that are invite-only (without much actual reason to be so)? What about community admins who decide to take their whole thing down, communities that break site-wide rules and get removed by site admins, etc? Does Discord Inc. make any commitments towards publishing discussions that have archival/historical value? How much knowledge is already irrecoverably stuck in Slack's bit bucket, as people flocked away to the next walled-garden chat app?
