Richard - my opinion is that it's ultimately up to you, but I would only consider doing it if:
a) you intend to go somewhere with that profile (i.e., add family members, possibly even spouse(s) and children)
AND
b) you have put in place some sort of Advance Directive that would allow someone to maintain your living profiles should you unfortunately depart from this Earth before you have the opportunity to properly pass along any living profile information you have amassed.
Just my opinion, of course, but I'd hate to put a lot of work into black privacy profiles only to have it wiped when I'm no longer here.
