Mate, I fucking wish for real that she's actually the one answering you, but just for the sake of the argument let me give you this info:
I have this friend, she's a cam girl. She sells chat porn (and some private stuff through whatsapp) on this website here in Brazil. The site relays how to contact "her" for a fee, you're then directed to her "private" whatsapp number. Early december last year she was kinda swamped with the whole thing, so she got some help. The people running "her private porn talks" now? Two gay dudes, also friends of mine. (How I found out about her, actually.) Yes, you read that right, a bunch of dudes pay to get her number, and have virtual sex with two gay dudes on the other end of that deal. (They also sell her vids through the chat, but the primary intent is virtual sex through chat.)
Like I said, I really hope for your sake it's actually her, but odds are... It's everyone but her.
