It wasn't completely raw but I remember it being fairly lax.
The reason the 2006 Turkey Slap Incident even became known was because it was shown on the live stream, captured in the Fan Diary here and then I posted articles about it (back when BBB had a news area).
There was a huge debate at the time because Ten technically didn't break decency rules because they only applied to broadcast television, not live streams (the laws have since been updated).
In a parallel universe where BBB doesn't exist, the turkey slap happened but no one found out.
