I've only watched since BB7, so had to go for Seany, who I didn't particularly like, especially as he indirectly caused Lesley to walk out with his juvenile pranks. In fact, the only worthwhile thing he did was pushing Charley in the pool, but even that was an obvious airtime grab.
The only other options I had were Sezer, Mario, Cairon and Govan - all even bigger pricks
