"Man is least himself when he talks in his own person. Give him a mask, and he will tell you the truth." ~ Oscar Wilde.
This is to say that anonymity has a way of setting us free. It gives us the ability to speak freely what is on our minds, recount information without filtering out information for fear that we may suffer attack or dishonor.
Whatever it may be really. Maybe we fear for our reputation, fear for our money or fear for our lives. Censorship is a knife blade held to the throat. Knowing who you are dealing with and intimidating them or putting them under duress for speaking the truth is the worst censorship of all.
When you have a platform that gives anonymity then you have the opportunity to present facts and information as much as possible with every inch of detail and YOU understand it.
That part is important too.
Remember that even if you are the masked one, with the ability to speak freely your mind that you are still only seeing everything from your own perspective and this can impede your ability to be open to others and receive other truths.
To thineself be true.
