Study finds there are nasty people on social media

[ArMaP]

It's long been known that anonymity gives people space and the ability to say things and to behave in ways that they wouldn't if they met face to face.  Basically, it removes some social accountability from the entire process.

Also, if I'm not mistaken (I can't find any reference to it), someone made an experiment, with some people destroying a car with hammers and baseball bats, and soon other people joined in the destruction, showing that if we see we are not alone in doing something we are more likely to do it, even if we think it may be wrong.
