Once a person joins the forum, they become a zombie. Not in the literal sense, of course. They may still have a family, a job... But they feel most comfortable on the forum, because the forum is not just the meaning of their life, but also their identity. To some, they may seem like a madman, a mentally ill person, an abnormal individual, but that is not the case. They can smile, have interesting conversations, read, listen to music. But even in those moments, they are still on the forum. The forum becomes a part of a person's life. Once it enters a person's life, it radically changes it, and the person may abandon a good, prestigious job, a profession, and may forget about everything they used to live for... These people do not go into business because they are content with little. Money is incompatible with the forum for them. When they are not on the forum, they are mentally there – constantly thinking about topics, going over answers, coming up with something new, and re-evaluating the old.
They are zombies. And like real zombies, they are difficult to distinguish from the crowd. They don't like to attract attention. While living in real life, they simultaneously live on the forum – that's where most of their life takes place. They don't want it any other way. And they can't.
