The conversation between human and AI assistant.
Why can't you send a DM to someone not following you on Twitter?
That makes sense. What about if someone has their DMs open to everyone?
Even if someone has their DMs open to everyone, you still cannot send a DM to them if they are not following you. The open DM option only allows them to receive messages from anyone, but you still need to be a follower to send them a message.
