Hello @tucsond friend. I am very sorry about what has happened to the young "Amanda" in your country, this is a frequent occurrence throughout the world, many young people fall for deception and then are blackmailed and harassed to the point of leading them to depression and at worst cases to suicide.

I think that the use of social media has caused a lot of freedom of action thanks to the anonymity that a @user profile provides in any of the known social media, so it can be said that there is no control over this.
