I wonder why you ask this question or why you need the data. For sure not all joiner will disclose their gender since its optional or default when creating profile and that’s one way of privacy.
I work for Special Bitcointalk Secret Service SBSS
GI department Gender Inspection
and I want to conduct secret experiment with all the 'joiners', and I need all this data so I can sell it and get rich quick.
This is a secret, so please don't tell anyone about it
Don't you Think Lauda is a female or its just Her/His name?
Lauda is controversial topic in this forum, and I don't know anything personal about this member.
I do know who Niki Lauda was
