The first thing we must remember there is no such thing as totally free speech. We can't yell fire in a crowded theatre. We can't give away defense secrets. We can't harass, libel, or slander another person. We can't make accusations with malice and reckless disregard of the truth. We must respect the privacy of private citizens. This laws have been around for many years and the Internet did not eliminate any of them, although some people seem to think those issues do not exist.
The existing laws on free speech, harassment, and libel/slander are generally adequate.
The problem is that enforcing such laws in the online world is very difficult.
If I were to personally print up and circulate a leaflet falsely accusing a neighbor of heinous crimes, that neighbor could fairly easily find me and successfully sue me, and perhaps take other legal action as well.
But if I were to utilize a website to make such an attack and make use cloaking mechanisms, it would be rather hard for that neighbor to find out who I was and take action.
Unfortunately, the Web makes it very easy to hide one's identity and easily and cheaply spread rumors and lies. Printing up and distributing leaflets takes time and money, and even involves some physical risk (if someone sees me doing it and objects, I could get punched).
The ease of the Web has encouraged many people to post slander. Many times social websites are used by kids to visciously attack other kids. (They wouldn't bother if they had to do it with hard copy.)
An added problem of the Web is that many hosting sites are overseas and beyond the reach of US laws.
Clearly, this is an area that needs reform.
It seems that supporters of the "unruly nature" side do so mostly on lofty principle, as opposed to any real substantiated practical results that benefit everyday people or the public interest. But those seeking to "tame" the web have many hard examples of abuse on their side. As mentioned, this is not so much an issue of "free speech', but rather protection against the equally legitimate issue of libel, slander, and harassment.
