I'm pretty sure its mental disorder. No normal person sits on the internet for hours on end and does this. I have a friend who is a psycologist and asked if this was some type of disorder. This was a possible answer.

Narcissistic Personality Disorder:

Having an exaggerated sense of self-importance

Expecting to be recognized as superior even without achievements that warrant it

Exaggerating your achievements and talents

Being preoccupied with fantasies about success, power, brilliance, beauty or the perfect mate

Requiring constant admiration

Having a sense of entitlement

Expecting special favors and unquestioning compliance with your expectations

Taking advantage of others to get what you want

Having an inability or unwillingness to recognize the needs and feelings of others

Being envious of others and believing others envy you

Behaving in an arrogant or haughty manner
