The lotto system goes by hope and what more, you would very quick see people coming here again as 100s including RMT bots take part in the lottery, knowing their is a lot of gil to be earned for sale, and also put those in the position of deciding the price once the next 1 person FC is sold to someone for 10 to 20x the value of the plot.

I assume the lottery is a way to try and get rid of player bots... and sitting somewhere having even less chance for getting a house as you don't need to camp anymore.

If you want to flush it out.. allow 3-4 clicks per day per plot only, it would first of all flush out 99.99% of the bots and it would also give you some time to actually play the game, instead of having to click a placecard all day long.
