It all comes down to the argument - who is responsible? Should groups be moderated?

Imagine if someone anonymous spreads a rumor that a certain man is a pedophile. Should that be allowed to happen, or should content be checked before it is shown online?

Or should all members of a group be identifiable?

Whilst I don't think there have been many problems so far with such content, what if it becomes ubiquitous?

My feeling is that, ever so slowly, we are seeing more and more restrictions being placed on internet usage and it won't be long before we have laws making it difficult to freely post on the web.
