Make Profiles on Lodestone be private

Why can't we make our profiles private?

My friend and I are being stalked daily and as soon as we do anything in game we get messages about how for example "We're levelling White Mage and Warrior together" And this person keeps refreshing our profiles and checking our experience gained.

The person in question doesn't even play FF anymore and yet because of the Lodestone we are stalked and tracked is there nothing that can be done?!

We have blocked him but he creates new accounts to message us. But if he was unable to check our accounts so easily via the Lodestone at least we wouldn't feel watched 24/7
