I don't recall this thread being started by fabiola! with the intent to prove her gender. She started it by asking if there are other girls into Bitcoin, and why it seemed there are so few.

It was, in point of fact, the "scam-alerters" who shifted this towards a well-then-prove-you-are-a-female thread. I don't see any reason she needs to (it's not like she's posting pictures of herself in exchange for loans or something).

I happen to think that this kind of thread is perfectly fine in the Beginners & Help section. It demonstrates the wide variety of attitudes towards women on this board, and can inform newbies on the subject (although, granted, those attitudes aren't all that different from many other online communities). It also servers as a warning to newbies on the methods of some scammers. I'd like to think it's at least somewhat welcoming towards woman new to Bitcoin, too. Seems on-topic to me...
