From recent comments and deletion messages by mods, MN appears to be trying to educate users on reporting posts and comments rather than troll-hunting, yet has made this more difficult by 'hiding' the means of reporting.
I would suggest that returning the 'report' button to the bottom of each post/comment, where it is easily seen would be more effective in encouraging reporting. Just seeing the 'report' option can act like a prompt.
Or is it easier to blame site users, whilst benefitting from the clickbait that trolls provide?
