Site as Adult???

[1Tamtam]

Hi there,
I;'m currently building a website, and have chosen nabble for the forum part of it. But it is showing as an 'adult site".
I don't understand why.
Here is the site: www.1tamtam.com
Here is the nabble forum: http://1tt.23835.n7.nabble.com
Thank you for your assistance
