Sabrina Bittencourt is the Brazilian activist who died recently after exposing John "of God"'s involvement in sex slavery, baby farms, and murder. A recent Facebook post by her son Gabriel reveals she was involved in the past two weeks working to delete internet images involving underage singer MC Melody and (if I'm reading this correctly) exposing "Birrthday's indigenous child trafficking network":

My Mother's last 15 days in addition to welcoming victims was to help take from social networks, Youtube channels for adults and porn sites all images of melody singer. She did this for free, if fucked up defending the girl and family in the press for at the end the lawyer of Melody's father and Bella talk that he was friends with bolsonaro and that it was better my mother not to take care of their career because she had Birrthday's indigenous child trafficking network. My mother tried to defend these parents from birrthday to turn into a fight against artists getting to "defend" a child as a political flag. She knows very well which side my mother was: from abused children. Melody's father and Bella dismissed the help of my mother and Felipe Neto and said their career would be suspended. My mother then began to target all the plan and partnerships that began for them, to create a larger platform with her team to help young Brazilian artists in vulnerability. It's full of witnesses of that and my mom's teams won't stop working.`

Here is the wikipedia for Melody, which mentions Bittencourt: http://archive.is/pklO9

And another article, mentioning Bittencourt: Pai de MC Melody diz não ser mais responsável por carreira da filha http://archive.is/r9BMS

"Due to completely this exhibition, we decide in common agreement and with the support of the youtuber Felipe Neto, who is a friend of the family, which I will not be any more person in charge for their run and because of wanting only the best for my daughters, knowing of their potential and what now two are adolescents who need more than never of the women's support in this new process of education, culture and art. The responsibility from now on for all this part is of Sabrina Bittencourt and team sweats and I ask that you listen attentively to the whole plan what they have for our family and what our daughters, they be a powerful voice for the changes that we want to see in the world!"

Apparently there was a scandal about the very sensual image of this underage singer and Sabrina Bittencourt, as a well known anti-abuse campaigner, was involved. Sounds rather innocuous, except this is what SB was working on in her final days and there is that mention of a child trafficking network.
