When a Question activity is posted and you select one of the options, what then happens in terms of the protocol? What is the expected ActivityPub representation of a vote on a Question?
Mastodon does the following checks on Create Note to identify poll votes: mastodon/create.rb at cff7d967f97b5119f9cf68f84973a8e36ec9d7c6 · mastodon/mastodon · GitHub
return false if replied_to_status.nil? || replied_to_status.preloadable_poll.nil? || !replied_to_status.local? || !replied_to_status.preloadable_poll.options.include?(@object['name'])

- Create Note
- inReplyTo exists
- inReplyTo is a status that is a poll
- inReplyTo is local
- inReplyTo’s poll includes an option equivalent to
Here is how Mastodon serializes votes: mastodon/vote_serializer.rb at cff7d967f97b5119f9cf68f84973a8e36ec9d7c6 · mastodon/mastodon · GitHub
id: ... type: Note name: <the exact text of the poll option> inreplyTo: <some status that is a poll> attributedTo: <you> to: <the poll maker>
Tangentially, here is Mastodon’s poll parser: mastodon/poll_parser.rb at cff7d967f97b5119f9cf68f84973a8e36ec9d7c6 · mastodon/mastodon · GitHub
Note that Mastodon does not use Question as an activity, but rather, as an object. So Mastodon will send out and expect Create Question.

it should be like a DM, yes
