It is a fair question to ask. If someone has a legitimate copyright issue, then it ought to be respected. So far, nobody has used the magic words invoking the protection of their copyright.

Filing a false claim of copyright protection is a violation of United States Code 506 C and carries a penalty of a fine of $2500, which indicates the person who has contacted the forum likely does not hold the copyright on the pictures in question.

If the model in question were to make the request in person, no doubt it would be respected by the readers of the forum.
