NSBC stands for the "National Society of Blacks in Computing". In March of 2016, leaders from
iAAMCS (the Institute for African-American Mentoring in Computing Sciences) decided to host a conference dedicated to creating a safe space for participants to receive mentorship, increase professional networks, enhance social capital, and plan their career trajectories. As a result, the National Society of Blacks in Computing Conference was formed.

A new group, Blacks & African Americans in Computing (BAAC), has joined the roster of student-run organizations with ties to Illinois Computer Science.
BAAC plans to celebrate diversity that already exists in computer science and other technological fields, but also expose minority students not already engaged in tech to the possibilities open to them, said Joseph Sieger, who is president and co-founder of the new group.

These are just a small sample of the black led organizations/groups that work for the benefit of black people and use the term
blacks. Most in their name like Blacks at Xbox team. I thought that student organization was particularly interesting, as they have both black and African-American in their name. As people have been discussing about the distinction in this thread.
To be fair, it seems like it's been black people discussing these terms recently in the thread and what they identify with. But sure, there has been plenty of people who aren't black and initially jumped on this thread to ridicule the group and there were those who miserably failed at grammar.
