That's a snapshot from the upload window. If they actually managed to upload it, it must have been a linkset with more than ten high poly parts. (The tri and vertice limits are for each part , not for the whole linkset.)

But for the sake of all that is good and fair, PLEEEEEEEEEASE DO NOT DO SOMETHING AS STUPID AS THIS!!!
