Claiming that there is a 'cover up' does not imo amount to
defamation because no one is being defamed. It would be a sad day
if one cannot spout consipracy theories, however absurd they
are.
The fact is, current laws, such as defamation laws, are already
adequate to prevent baseless and specific allegations about
identifiable individuals from being published. The IP address of an
individual can probably easily be discerned if the server is in
Singapore. If the server is overseas, then the issue is moot
because then those laws would be in effect, whatever you legislate
in singapore. Now if the server is located in countries like the
UK, then, provided that there is a good and credible case, one can
sue in defamation as well.
I therefore see no good reason to require registration, except
perhaps, and I am being paranoid here, to facilitate extra judicial
monitoring, intimidation and interference.
It is said that power corrupts, and absolute power corrupts
absolutely. I agree with that totally. The problem with giving
governments power is that power given is very difficult to take
away. I therefore have a strong inclination to resist giving
Governments more power without a darn good reason. The case has,
imo, not been made.
