Jillaine, no protection needed. The Holocaust project only has recent profiles, for obvious reasons. It manages those that are orphaned and may take over management of those whose managers are unresponsive if profile improvement is needed.
This project differs from those where protection is often an issue - these are all very recent profiles and about 95% of them died within 3 years of each other (with the same cause of death). Most are siblings or cousins of ancestors of people living today, rather than direct ancestors. They aren't proliferated widely across the internet, so duplicates are very rare. Also, being so recent, it is rare to find them common ancestors of multiple WikiTree members.
The project box is more than just notice that these profiles belong to a project - it represents a badge of honor for them, so it would hurt to have to remove it from profiles managed by their family members, unless there is a sticker to replace it.
