it's d3-- would you really consider taking any chance on losing your autobid (or good seeding in the NT) to let in a 100+ RPI 16-seed who's going to lose in Round 1?
you'd get $250 for recruiting for your effort, if you both made the tourney, but you'd hurt your own chance to win games, improve team prestige, and potentially earn even more postseason money. seems silly, beyond the fact that it's obviously cheap, and likely hurts a human user elsewhere by taking away their bid...
