+# ethics statement
+
+It seems that some splinter groups are not well acquainted with the norms of
+publishing data on the web.
+
+Publishing your toots/messages on a server without marking them private or
+requiring authentication and thus making them available to the web is an act
+of affirmative consent to allowing others to download those toots/messages
+(usually by viewing them in a browser on your profile page).  If you don't
+want your toots downloaded by remote/unauthenticated users on the web, do
+not publish them to the web.
+
+If you publish them to the whole web (and your home instance serves them to
+all comers), do not be surprised or feel violated when people download (and
+optionally save) them, as your home instance permits them to.
+
+We do not have a right to be forgotten, as we do not have a right to delete
+legitimately-obtained files from the hard drives of other people.
