My guess is that that's just normality setting in. Back then, the internet wasn't for everybody, you didn't do "normal stuff" on it, it was a very separate domain. Today, the internet is about as special as a side walk, everybody is on it, you can do anything on it and all the normal people and all the normal problems have come along with the change.
In society, witch hunts have been a thing for quite a while, I think the web mostly just didn't have the opportunities to show its witch hunting abilities in the early, pre-mainstream years.
