> I don't want people on the internet to be able to drudge up out of context statements I made 10 years ago by googling "site:discord.com ". We’ve had public and private forums - or more often, private sub-forums within larger public forums - forever. I don’t see why you can’t achieve the same separation on Discord, as long as they allow admins to explicitly set indexability(?) for each channel.
That seems reasonable enough technically, but I doubt it would work out that way in practice. Most users would probably treat all Discord channels alike. Those who don't understand the setup would carry on as they always had, many of those who do would find it easier to treat all alike (if for no other reason than that the setting could always change).
This is exactly what used to happen on “legacy” forums, too. I’m all for reasonable guardrails[1] but at some point you have to just let people take some individual responsibility.
1. Alert users who are posting publicly, allow them to disable posting to public channels in their account settings, etc.
