There's your issue. The moment housing becomes available, the housing bots get RIGHT ON IT like moths to a flame. I've seen them straight teleport to the place right when it's been opened, and they've been able to snatch it up before any other player can get to it.
While a housing rush was a natural thing since Shirogane opened up, I'm full support for the Lottery System that their team has made. The Lottery System also heavily taxes bots in the fact that it's at a major operating loss for the person handling his army of bots, so it helps make it that much harder for them to just steal the plot outright and try to sell it via RMT.
