Do You Know On 'Big Brother' On Channel 4 How Davina Says 'You are live on channel 4 please do not sware' ?

i dont think its the law, its more of a thing to do with watchdog regulations, as if she doesnt mentioned it and someone does end up swearing, viewers may be offended and if they complained. channel 4 would be blamed for not telling davina to mention "not to swear" and they could be fined. if that makes sense lol
