It makes no sense to me how those posts are valid. I included the post numbers in there for a reason.
Here's the facet that I'm trying to show with my numerical point: if a very general thread (i.e. Do you need cash for everyday use?) already has already 400 replies... enough has been said.
If you're not going to enter the topic with a nuanced reply then all you have are bland, repetitious posts.
Just a thought they may have been left alone with it being a self-moderated thread. Still should have been purged or it's otherwise just promoting the creation of self-modded spam pools. I've gone thorough quite a few threads like this in Bitcoin Discussion - where I go back over the last week and report probably 16/20 posts on a page. I have taken to writing a short novel for some of the reports though.... hmmm maybe start with haikus.
These are just a couple examples of something I would type when I go through some of these threads.
Redundant post - Generic repetitive content stalls the discussion - low value adds nothing new - sig spam
Redundant post - quoting to feign conversation - adds nothing new to the topic - spam
