You said, " Just check that post is 30 minutes old before upvoting."
Why do you think it's good to wait for 30 minutes? Don't you get a bigger curation reward for being one of the first people to upvote new content? If this is the case, waiting 30 minutes would get you a smaller curation reward. Or, am I wrong about how this works?
You are wrong.
You will get less reward if you upvote within 30 minutes.
Where does it say that? How do you know? How did you figure that out?
