Also a few housemates mention how they had to go abroad for hiding before entering the house. Richard (BB7) said he was in hiding in Belgum for two weeks.
It's funny how big of a deal hiding was even ten years ago and that most of them had to go to different countries whilst in hiding so the papers wouldn't know who was going in. Nowadays, they probably go into hiding like 3 days before the series starts and it's probably in a local hotel near the BB house. By then, they'd know everything such as the theme of the series, the eye, etc. I miss the old days
