An acceptable Comment will pass through this filter:
Is the writing understandable?
Does it genuinely engage the blog post or a previous comment?
Is it a sincere statement, a valid question, a justifiable comment regardless of position?
Does it avoid profanity, name calling, character attack, slander, threats?
To date only one comment has been deleted before posting, and that one because, no matter how strongly one feels, calling child protection or MCFD mobsters or organized crime won't fly here.
