The type of over-pumping topics usually contain many pyramid quotes, which are almost non-sense discussion, inside.
Hate to say this, but pyramid quotes hurt my fingers and take lots of my time to scroll computer mouse to scan and find worthy posts to read.
It's hard to assess one post is meaningful, constructive or not; because it is only value for each reader who has specific demand and knowlegedge. One post might be meaningful for someone, but is un-meaningful for others.
Nevertheless, pyramid posts are definitely undeserved my time to read.
