@feditips @Zeugs @mho @jwildeboer @tchambers @FediFollows there is no privacy being "sacrificed" here, that's my larger point. If the Fediverse ever becomes big enough, *someone* will index it. Having it "opt-in" is like asking "pretty please leave me alone" to 3-letter agencies and Big Data miners. Do you think they'll honor it?
Those that need real privacy should not even be on Mastodon and should use only provably secure communication channels.
