I’ve a Journalism degree and don’t feel qualified to “rate” these comments. Esp. not seeing what they are commenting on. Editor’s instructions below do not help. If a comment appears particularly nauseating I may punch the appropriate buttons. Otherwise it’s random. 
The Dispatch does what it can with available resources. Civil Comments was adopted to avoid expense of employee(s) doing the ratings. The result is pronounced good by the Dispatch.
Perennial comments by righties complain the “left-leaning” Dispatch censors their contributions…even as it publishes the complaints. Lefties may be censoring the righties…I don’t know. But the Dispatch, for the above reasons, hasn’t time to edit the righty-lefty thing. I suspect lefties are more prolific. 
There are good anonymous comments, but comments by unknown persons will never have the same value as those by the named.
