I think it's pretty straightforward, Helnar.
You don't say or do things because you know that there are social repercussions. My boss is rude to my coworkers, but I don't say anything because I could get fired.
Remove the social repercussions (via anonymity) and you have no reason not to do those things. All of a sudden I can verbally abuse my boss as much as I want.
Doesn't mean someone is socially dysfunctional, it just means they're free to say exactly what they want to say without any inhibitions.
