Violet Blue flags up the "adult" problem on Google Plus

I don’t think a lot of people realize yet that the default photo and image albums are Picassa, which has zero tolerance for nudity or borderline content, and does not offer users content rating controls (such as the ability to mark things as “moderate” or “restricted”) to remain within the Picassa/G+ content guidelines.

So nobody under 13 is allowed in, but don’t expect there to be anything there than content for a 13 year old. Riiiight.
