Quoting "Daniel R. Tobias" dan@tobias.name:
While the trolls and vandals do some harm, a lot more harm is done to Wikipedia, in my opinion, by the Judge Dredd types who see themselves as the thin blue line against trolling, vandalism, and anarchy, and have no compunctions against acting as judge, jury, and executioner against anybody they see as an enemy, or as somebody aiding the enemy.
Human history is full of cases where people decided that some enemy (real or imagined, significant or exaggerated) justified a state of war in which normal civilized, genteel considerations no longer applied. The results, which include the Spanish Inquisition, the Salem Witch Trials, and McCarthyism, are often judged harshly by later historians. In the throes of a moral panic, people can enter a state of hysteria where they undermine the values that made their community good in the course of allegedly defending it, like the soldiers who destroyed a village in order to save it. A Twilight Zone episode, "The Monsters Are Due on Maple Street", provides a fictional illustration of the tendency of a community to be its own worst enemy.
There are many problems with the above. First, we are the thin blue line against trolling, vandalism and anarchy. There are masses of people who want nothing more than to use Wikipedia to promote their agends and goals. And we cannot let that occur. There isn't much of an issue here of a moral panic. The people we are dealing with, such as Brandt, Bagley and Barber will stop at nothing until they get precisely what they want out of Wikipedia or destroy the project. There is no acceptable response other than to block them on sight.
Although I disagree with Guy as to how we should treat people who are willing to deal with them, it is posts like the above that make me have some sympathy with Guy's position. Spend too much time on WR and you'll forget what these people have tried to do to Wikipedia and the lives they've ruined in the process. And frankly, to compare good faith attempts to keep this project safe from the people who have explicitly stated they intend to harm to the Inquisition demonstrates a lack of perspective at many different levels starting with the minor detail that we're not killing anyone.
