As much as people in real life

Both can lie and do petty things sometimes. I met some online friends already and they were pretty much the same in real life, but I didn't go meet them all alone in some secret place at first, like some people I know...
I know girls silly enough to meet some guys at their home without really knowing them, luckily for them, nothing bad happened but just in my city a woman disappeared that way and she apparently knew that Internet friend for one or two years. I think one must be careful. So yes I trust them, but I keep in mind that most of them are still strangers to me.
There are people that are also maybe.. a little too intrusive and too soon in the relationship. Bordeline psycho. That doesn't mean that they are bad people, but I come on forums to have fun not to be subjected to an interrogation about why I didn't log on that day and what I was doing with whom etc etc...and making a scene about it. I think some people are sometimes ...quite intense.
