The nuance this misses is scale. FB wouldn't just need to block people who are reported, they would need to have a team to manually investigate all claims. Otherwise it's just another tool in the harassers' arsenal. Their automated systems (which exist) haven't caught this, or they wouldve been disabled already. Alternatively, the number of people needed to investigate every reported account is absolutely massive.

And yet, some stuff does get blocked, and even manages to get blocked routinely or on a hair trigger. I thereby stand 100% by what I said and whatever moral implications might be inferred... but can now add that those same decisions / priorities--during the time when you were part of that exact team, though accepting some generous room to quibble if you explicitly quit in protest or spent your time on the inside fighting for some kind of change (and with maybe a narrow exemption for "I really really needed the money", as I get that some people are stuck)--also show your true colors (which you likely, or course, already realize, but I think should always be explicitly stated).

In China 2 million people work directly on this.
