people post every second
Which of the following do you mean with your phrase?
- a group of people collectively posting every second
- each person in a group of people posting every second
If you are referring to the first one, then I would say that nobody in Twitter posts every second.
If you are referring to the second one, then I would say that people have the right to use their Resource Credits whenever they wish for as long as they don't harm or annoy people (though I acknowledge that people could use their downvote power as they wish too).
