I guess this year, as they charged people to vote on the first night they might be on iffy ground if they just put the 3 rejects in after the vote decided on tom (

) so I would maybe expect some of them in next years, if there is a next years as they appear to be purposely trying to kill the show
Showbiz was given another chance after the stupid launch night twist when he was technically evicted. But this was probably because there wasn't a public vote for it. Same with Kinga.
Having said that though, there was a normal eviction vote for Nikki and then she was put back...did BB actually have to refund people for that? I don't remember ever finding out, surely they got a fine for misleading voters at least
