That may be true but there are bad blood among a few people that a clean forum cannot resolve and the said problems may occur elsewhere, like FB Twitter and other places people's lives can get ruined there. Almost everyone here has an account at one or both places and will go thru lists of friends and family of an adversary and deliver dirt.
The best thing is to never use FB to contact an adversary or untrustworthy person who has no good intentions, 80% of Topix troubles regarding subject has involved a social media site as well...
That and keep all posts and pics for friends only and keep the friend list private. If one is unsure of someone on their list, can always restrict them.
