tRump doesn't have the fortitude to rise to the challenge of how to continue moving this country forward.  We can expect that he'll cut and paste his mud slinging and name calling.  Why hell, he's even brought on his campaign board the guy who created the Willie Horton campaign ad that was used against Dukakis.  Yep, that's where the un-presidential campaign is headed.  Voters will buy tRump in his own sewer.  I can't wait to see Hillary unleash Bill.  American voters hated the Republicans hypocrisy when they tried to impeach Clinton and it didn't work.  I wonder if the Larry Flint- style  machine will come out of the woodwork.  LOL

No

Yes, that is the review process we go through to comment. The three comments we see are determined by random chance, not by topic, author of the comment, or social psychology. The idea is you take a step back, look at some other random comment in another thread (with a click available to catch context), and rate that one as civil, or not. 

I don't know about social engineering, that may be a bit too grandiose. I think of it as all of us pitching in to moderate, instead of depending on one person, or some software to screen words and phrases. We each spend our 10 second, and the system works better. I hope.
