What do you think of phony online personalities?

Does this sound familiar?

Someone, either Girl or Guy, is miserable with their work, finances, dating life, or anything else. So when they go online, they create a fantasy world where they have:
* The perfect work environment where they get everything they ask for and everyone obeys them
* The greatest track record of stock trading, picking up dates, you name it

And based on their god status within their online fantasy world, they respond condescendingly to other posters. They ridicule other posters for perceived mistakes. They act so smug and superior to everyone else. They say things that they would not have the courage to say to someone's face in real life.

It is one thing if their online personalities are obviously intended as a joke, as obnoxious as they may be. But is it healthy for disgruntled people to represent themselves online as something they are not?
