I think social media could be the Achilles heel…. But I would hope after the first few not-tech savvy idiots tried it and landed up with a police record and dragged through the courts, that’d stop.

Ultimately you can find out almost anything if you want to look hard enough. I could find out Miss R’s name, but that takes effort and most people are lazy. They enjoy having information given to them and doing no additional reading or thinking. Most people just want to be told who the villain is - and that’s really the difference. The occasional person finding out is different from an ill-informed mob demanding justice via social media.
