If I understand correctly, you know ActivityPub quite well ?
Could you then please explain (here or on a blogpost) who can see what when a poll is made and people on the fediverse answer it ?
Namely, who can see the individual votes rather the aggregated ones...
@lienrag well, I can tell you the way it is defined in ActivityPub, but Mastodon breaks it in some specific ways.
If you have a fediverse account, you can quote this note from your own instance. Search https://cosocial.ca/users/evan/statuses/115871993802211300 on your instance and quote it. (Note that quoting is not supported in Mastodon.)
