You misunderstand.
When you have been here 3 years you also will quickly identify fakes.
People come here to pretend to be something they are not.
The girls here take those people into their confidence - build friendships, only to be hurt by that person.
After a while these people become easy to spot, the stories are similar, usually there is a fatality or similar, pregnancy gets bumped forward by months in the space of a couple weeks.
Also another thing to bear in mind is that some girls know others from other websites.
Sometimes a comment that looks "nasty" actually isn't because the person it is directed at knows the tone in which it is delivered.
For example a while back terra and dalicia posted about each other seemingly really nasty comments. They weren't and the recipients knew that yet to an outsider (of that conversation - me included) it was like woah what until you read the whole post and understood.
