Got it, thanks. I've been trying to categorize and review the different approaches. If it's not too much trouble to reply once more, was there any form of 'moderation' involved in the grand scheme of things? Like a flagging system for bad posts or some kind of behind the scenes 'review' process where comments/posts violating terms/conditions/standards would result in deleting a post or eventually banning an account? Thank you for your time!
