Not sure if it counts as pig butchering or has another name (it’s extorsion, for sure). In my country recently there has been a surge of what we call nude photo scam. The strategy begins the same, they lure men, mostly middle aged, but instead of asking for participating in a crypto scam, both parties have a “passionate” chat and exchange lewd pictures. After that the “father” of the girl appears, saying she’s a minor and that he wants something in exchange for not pressing charges.
The scam is so elaborated that at some point fake cops in sets that imitate precincts make calls demanding money or the victim will be exposed and go to jail. Even if the victim pays, he is asked for more money and the losses may amount to the equivalent of tens of thousand dollars.
AFAIK it is operated locally. Victims and scammers, all from Brazil.
