Is there a number of reports needed to get a comment deleted? Or is it not automatic?
You may want to check the Statement of Rights and Responsibilities and see if the comment actually needs to be reported.
I believe it increases in moderation down the list.
Spam or scam
A lot of users spam other walls with their Facebook pages or groups.
Contains hate speech or attacks an individual
This could just be a heated argument between two users with nothing better to do than argue over Facebook.
Violence, crime, or self-harm
Here it becomes near a legal issue so I would believe the moderation is very tight here.
Nudity, pornography, or sexually explicit content
Same as above. Without even the need for report. I have some friends who were models that placed up their semi-nude shots only to be removed immediately after.
There must be some sort of issue-handling service that rates the reports. Because there were many times that I have reported comments only to realize the page admin could have just removed the comment.
