Also, think about the practicalities. If someone wants to do something about their request to remove a post being ignored, they will have to take some legal action to try to compel removal. If this is a trans-national situation, this means they are going to have to get an attorney in a foreign country and pay the fee for that and then sue. The likelihood of that happening is very small. Unless the person has deep pockets, they likely will not pursue the issue.
The legalities will depend on way to many facts to really figure out based on a vague hypothetical (and if the facts were concrete, at the moment I don't have the time to discuss how this might play out).
