I think it's less about attention seeking (that's just a useful byproduct) and more about trying to stir **** and wind people up, personally.
What I find fascinating is that they say this is what they're going to do, all of the housemates sit there and discuss that that is what they're gonna do (unlike the ****ing pathetic supporting cast of CBB11 who allowed themselves to be trolled) and how they should play them at their own game, and then Austin succumbs to such blatant baiting

Spencer's there saying 'I didn't realise it was Austin's water, Austin's H2O' and he falls into his trap and gets irate???
