Cause lots of people find her mockney peggy mitchell schtick entertaining...

Ever since c5 took over they have been extremely manipulative (the last c4 series with Josie's pass to final was, too). C5 desperately tried to stop bb12 Aaron from winning, demonizing him, humiliating friends and family home, covering up rival Jay's poo in freezer gate, booing crowds, bringing in love interests Fay's over protective sister etc. However C5 failed and Aaron won. Since then C5 has been even more manipulative to rig nominations. It's pathetic really.
