What's an example of a page Facebook took down, or an account Twitter took down, where you think they were in the wrong?
Interestingly, Facebook actually got dinged from real news outlets because its algorithm was ranking stories from theAntiMedia (and other conspiracy sites) higher than those of actual journalists during events like the Vegas shooting. So that might have played into it.
I can’t tell if your question is based in simple curiosity or implies some form of skepticism that mistakes were made or that problems actually exist.
