I am having the same issue, I believe this is a fairly recent change, and I personally am very upset about it. I would reccomend reaching out through the contact form. I hope that with enough feedback from their user base (primarily made of people doing in depth and/or fictional trees) that they will reverse this decision. Their faqs say that this is for privacy reasons, but again, when most of the trees are fictional- this should not be a big enough issue to take away one of their best features- being limitless.
