Obviously, and in any case an anonymous person is posting about another anonymous person. The point I was trying to make is that in the absence of libel laws you can make untrue statements about identified persons that cause them actual damage. I’m not sure if this is a different sides of the Atlantic thing or whether you are deliberately misunderstanding the point I’m trying to make, but I could extend your argument to say that the Internet facilitates fraud and blackmail, so we should stop bothering to enforce laws against fraud and blackmail.
You haven’t explained why a law intended to protect people who criticise the government has been extended to make it possible for the media to wage campaigns of falsehood against individuals.
