Yes, but in this situation it's generally different in a way that tends to benefit OP.

The First Amendment tends to make the U.S. less prone to have laws that limit your ability to share information once it's out there. In contrast, the EU has adopted many digital privacy protections that strongly regulate your ability to share information about somebody else, including their image.

Also, "blackmail" and "extortion" tend to be a crime in most developed countries, even if the precise details differ.
