Okay, so, leaving the other garbage out of it, you are saying that people have "fake courage" online to do what they would not normally do in their real lives? What do you think the purpose of this behavior is? Is the person looking for attention of a sexual nature? Or is the person so desperate for attention that it just doesn't matter what kind of attention they get? How about if it was your spouse online behaving in this manner? Would you be okay with it? Not just your GF, but a spouse, someone who has taken vows to be faithful to you and to respect you.
