The comment I was responding to seemed like a blanket condemnation of anonymous submissions, so I felt like a blanket rejection of that statement was in order. With regards to protecting whistleblowing versus people starting dangerous rumors, I think we can safely err towards accepting anonymous submissions without scrutiny since the community is already fairly skeptical.

I don't feel compelled to sympathize with Facebook/Google+'s business cases. I'm not criticizing their business acumen, after all.
