If its on the internet it must be true
If it's in person, it must be true.
Internet doesn't make people more liars than if we meet them in person. We judge their truth not because they are behind a screen but because we know them in some way.
Those we don't know, internet or not, it depends on what they say. Saying one is a billionaire or have a mansion wouldn't make me question the same as if they said it in person.
If they said in person or online, they will commit suicide (had that happen on another site where lgbtq preteens etc were upset cause their christian parents didn't accept them), I wouldn't think their lying.
We (chatters)could have thought she was lying (internet or not) but the majority of us knew of she was not, we could have helped her. We lost nothing if she were lying. She left home and we tried to get her to go to the police. We didn't know her family situation but her father said he's taking away all her electronics. That's the last time we saw her.
Of course, I don't speak to people in that extreme situation (that I know of) but it does teach me real people use the internet.
