I see what you're saying, and if these were small little online groups of, say, ten people, perhaps I'd agree. But one issue here is the audience size it gives people. Media guidelines (although they rarely follow them) say that you shouldn't publicise the names or images of people who commit these crimes, because that's a large part of what they want. The mainstream media are complicit in this too, and they should shoulder a good deal of the blame for that. Online forums are an easy target for the mainstream media because it means they don't have to examine their own part in the problem, but that doesn't mean the place where these events are initially publicised and encouraged shouldn't be tackled too.
