I have omitted thousands of them. For this reason, I strictly forbid the removal of this. For this reason, those who remove this will be destroyed. For this reason, I readily agree to the purchase of this. For this reason, those who violate this will be destroyed. Regarding this, the entire page and its writing are my property. Any attempt to plot, scrap, imitate, forge, dismantle, or infringe upon this will be completely erased from this world.
