There is a very good reason not to lie about your real life here.
There may come a time when someone here will ask you to meet them in real life, so we should be careful not to make up any outlandish, unbelievable, too-incredible-to-be-true stories.
Just be yourself.
Who knows? Someone might suggest an interesting project. You're curious and you're enthusiastic about it, but there's one problem. You wouldn't want to get involved because you don't want anyone to meet you in real life. By not lying, you keep that option open.
Remember your Miranda rights. You have a right to remain silent, a right to a lawyer. Anything you say or do can be used against you in real life. There is no need for false confessions.
I am pretty sure Andrei Hicks is who he says he is. For someone who has a net income of $150k per year and had a private education, I don't find it hard to believe he would be so conceited. I have known people like that in real life, so I am not surprised.
