Yes there was no counter arguments, no discussion of both pros and cons.
Annonymity can be useful and justified in a number of cases.
1. Where the person is speaking the truth and has a genuine fear of retribution and has a need of protection.
Whistle blower legislation goes some way to giving that protection, but it doesn't prevent the midnight visit of people with baseball bats.
2 Where there is a huge discrepancy in power. I am thinking of situations where large business enters a community and runs rough shod over them. Search "Ok Tedi environmental disaster" as an example of a company exploiting powerless people.
3. Where wrongs are happening but smart or rich people can hide behind the law and avoid prosecution. As an example ask almost any police person they all know of criminals walking the streets who cannot be prosecuted due to insufficient evidence. And we have all seen injustices such as public prosecutions of people where they walk free because they have a clever lawyer who can twist the truth.
However we need to be able to block the anonymous trolls on the web who indulge in abuse and malicious behaviour. We need to protect vulnerable children from predators and we need to be able to protect ourselves from clandestine attacks via the web.
