Call it something like greentext or confessions or something. Anyone posting is automatically set to Anonymous with no link whatsoever to the original account for admin or users to track or in the logs/activity pub etc. Like the person will not get replies, notifications on their account for the post, or the ability to reply as Anon. Simply streamline creation of a throw away account using the existing credentials of an existing account for post access and to give automod a chance to act. Maybe bar new accounts or below a certain threshold of engagement.
I keep seeing people go to the effort of creating a throwaway account to say or post stuff they want or need to externalize on the threadiverse. I’m willing to bet that for every person that goes to that much effort, there are likely somewhere between 10-100 people that lack an outlet and motivation to do the same. Greentext is just a mutual pretext on my part for genuinely caring about people under pressure right now and in need of an outlet in a way that is not really well supported by the fediverse or activity pub.
We are small enough here that regular names and people can hold meaning in familiarity and memorable history. Kind words and social interaction anonymously from these may hold considerably more value and meaning within this social dynamic that is not afforded elsewhere.
