I'm quite surprised at the number of users calling for censorship on <u>Hacker News</u>....
Don't be fooled. The technical design of the Internet and its serious non-resilience to spam, malware, and other various opportunists (because we all trusted that Internet users were reasonable people) should show you that none of this was in the original vision. "Be conservative in what you send, and liberal in what you accept from others" worked because everyone respected that without enforcement, and there was no crowd demanding the right to be liberal in what they sent.
