As @coolcryptovator states, these kind of threads are not about merit at all, but about complying with campaign quotas. The threads are born stale from the beginning, but serve their purpose for the spammers.
In general though, it is not easy to create original content that differs from all seen before. Most of the topics have been talked about at some point or other, and what brings something new is a good brain racket, a different perspective, or some recent updates on the topic at hand.
