My police nephew says unless swears or names or photos are used... nada.
So saying things like "breast cancer magnets on a purple mustang look like [censored]!" (Which totally targets nobody but actually targets my wife directly) .... is nothing police can act upon. He said being "mean" is not breaking a law.
The stuff they do is even more cunning than that. To explain to a third person who doesn't know our life or house or family composition is nearly impossible. In other words it is so specific as to seem generic and inoffensive to a true "stanger" to the situation.
I never thought as an adult I would know of someone so evil as this woman.
Oh, another example... lets say my wife is in a sales field for facial products and she posts a special sale on two bottles of a green tea facial clenser... well the woman will post for days about chemicals in our bodies and the will post a toxic sludge meme in a green barrel with the same sale star design as my wife's business. So notice how nothing is exactly named or pictured but the themes of design and color and topic are used so strategically but generic to a "moderator". Whereas people with my wife and her in the similar group of Facebook feed will see the intended "connections". So a true defamation case would look "thin". As far as they would claim "coincidence" to the posts rather than malice.
So cunning. And problem is that this lady is "connected" and other women fear her literally financially.
