The automatic ganging up on Tiffany was just bizarre to see. Anyone with an ounce of common sense could see it was all a bad misunderstanding off the back of some genuinely bad news. Tiffany didn't do herself any favours after they had all had a go at her, for instance calling Angie an old bitch, but they had played judge and jury well before that. John leading the pack. I have to say I don't think he was doing it deliberately, maybe he was more invested in things having being in the diary room with Angie, but the way people followed him so easily was very odd. I guess being in that house for only a week has sent people mad, or when the event appears to justify it people's real feelings about anyone will come to the fore i.e. they didn't like Tiffany anyway, even if she hadn't really caused any trouble up to that point. Or maybe the majority of humans simply follow the leader mindlessly - explains a lot of the trouble we have in the world!
