The problem is not the number of logged in users. There have been more than twice as many before.
The problem is that the current server code has issues.
1) The spawn engine is buggy. Due to this, a lot of spawns don\'t work or cease to work after some time.
2) The NPC AI is buggy as well. Due to this, MOBs go astray and get lost somewhere in the map.
Due to these reasons, there are most of the time almost no MOBs to camp, especially not lower level ones.
Therefore, it\'s simply one of the many things that don\'t work well right now. The devs certainly are aware of it, and maybe it\'s fixed in the next update.
To add to the problem, the quest system doesn\'t work, so there is indeed virtually no source of income, especially since the accessibility to the platinum mines has been severely reduced.
However, there is no way any thread like this will make a difference.
