That makes sense. If the pages become too detailed it´s also a problem. It looks to me like the solution you´ve chosen is the best one. You mentioned Staff were already a bit involved and agreed with you. If reasoning with him, maybe you can talk to Staff again, and ask them to speak to Jean. Their status does give them some "influence". Presuming you adopted the wiki, Merrystar is who handles the adoptions, and she´s very kind and helpful. If you ask her help, I´m sure she can do something to make the message get through. She of all people will understand your concern about loosing a contributor such as this when the wiki is being rebuilt.

And then there´s always the blocking option which you want to avoid. Don´t feel bad. You´re not being unreasonable. Most admins would have already blocked him by now and you´re giving him second chances.
