It is always best if you can resolve this problem on your own. Reaching out to him by email was a good idea. However, if you cannot resolve the issue to your satisfaction, please reach out to a WikiTree leader and we can help you get things back on track.
You should be able to delete yourself from any profiles you wish, even if you are the sole manager, as long as the individual is deceased. If you are the sole manager for a living person, you cannot delete yourself. However, if you reach out to a leader we can help you resolve this.
Sometimes it's very difficult to understand another person's way of thinking. Remember that the WikiTree Honor Code asks us to always assume good intentions. Perhaps he (wrongly) believes he is doing you some sort of favor. Maybe all it will take to resolve the issue is to ask him to stop with a brief explanation as to why. That may be idealistic thinking, but let's see what happens.
Please keep us posted on what happens, and again, please don't hesitate to reach out if you need direct assistance.
