It's not going to work by sanctioning the person that made the invitation. I want the tone of moderating actions to not be exceedingly adversarial.

My assumption for making the decision in allowing inviters to moderate their invitees is that theoretically they have a closer report to them outside of the website, and as such the moderating activity will happen out of band (ie, a face to face discussion, a private message, etc) and if that fails, they have the latitude of operating the moderation actions, like removing the offending post.
