Facebook I hate cyclists group infiltrated!

I do think there is a difference between those who have already committed some act, such as a deception, fraud, scam, etc... and those who merely communicate that they are thinking about it.

Let's be realistic, what Lynchman did wasn't actually a crime and boils down to "making shit up on a forum". Conversely, this guy has been threatening violence - fine if it's all pub talk, but it could indicate illegally poor driving, which is a crime.

I don't think either case should have identifying information bandied around because that sort of vigilantism should need a clear indication that some great harm will occur if the person isn't tracked down, but if one of them should it's surely this man who is a potential danger, rather than Lynchman who did an emotional wrong but was no operating danger to anyone?
