The people who are "members" are simply putting money into the developers pockets and they think they are having fun clicking polygons for many hours of their lives.
They have been sucked into the game from when they first started as free members and are now brainwashed. They can do nothing but play for many it is their life.
The game itself is very poor in graphics and music and these poor soles that have become stuck and can only hope to be hacked so they can stop playing and see their madness.
