A have had a statement blocked because I used ‘shill’ when referring to those who post false and misleading information in these posts. Note that shill usually implies pay but motivation may come from owning stock, working in the area, or other connections but I think is a proper definition and not derogatory name calling.
dbsb3233’s comments here are reasonable that may overly pessimistic and incomplete but should form part of a conversation. 
I have contacted the Civil people who do post guidelines and asked for a rating scale from 0 to 10.  There are many comments that are only partially civil but contain ideas that should be part of the conversation. I have concerns about the quality of the algorithm that cannot use the additional rating information.
