Like your ideas. Sadly, the reliable blackmailing-tool isn't available here because of Patreon.Maybe a mix up in communication? Maybe she is tricked by an unscrupulous character?
But talking about: You know Fashion Business? They always "blackmail" Monica, but it is still allowed. I can not get it exactly, but maybe it has something to do with the fact that the girl has to come up with the idea of offering her body and/or her liking it at least a bit. But no, these aspects are not convincing.
Can somebody explain what makes it ok for Patreon?
