The science of opinion ...

mapman,

I think the seemingly mindless meanderings of a certain poster and other posts made in this thread (and other threads) more clearly illustrates the concepts communicated in this paper than any planned demonstration could ever hope to achieve, and to that end, it will meet its educational value to those that want to learn.

^^^ But then there would be mostly blank pages.

This looks like it was published in  an on-line  forum.  As a one-time experimental psychologist I would say that this paper does not meet basic standards for publication because of the lack of documentation of the procedure followed in its experiments.  I could not figure out at all what was actually done to the subjects to get the data. Then the authors cover this up with an elaborate model which seems to be excessive for the basic points it tries to make, which don't really show anything new.  In other words rubbish research.

The problem with that is unleashing unbridled censorship whenever an OP does not like a post. I would be against that. 
Rather, anyone, on most browsers at least, can already flag posts for deletion that violate stated Agon guidelines, like spam, or being abusive to another among others.  So everyone already has the ability to help police the site based on the rules if they just care enough to take the time to do it.
