I’m already eagerly waiting for the time when Bleromer admins have to deal with parallel fact checks for “Vim is better than Emacs”, “Emacs is better than Vim”, and “Vim and Emacs boff suck. nano is tha best editta evar!!111!”
A bit like the one time when a (German) comedian quipped that it must suck to be a god and receive prayers from soccer fans who pray for the victory of “their” team.
To actually have it work after the post was made you'd have to use the Update activity which I don't think Pleroma supports.
