You're pretty much spot on there Sticks in your OP. The mob hatred synonymous with BB these days has risen as the general qualty of BB housemates has fallen. Ever since BB4, the producers seem to have converted BB into more and more of a freak show. They purposely put housemates in there to either cause conflict (eg lets put in someone who hates gays/immigrants/women/men etc, etc and then put in the most flaming, brazen object of their hate) or pathetic attempts to engineer some on the telly sexual fumblings (eg lets put in a bunch of self-obsessed, sex-obsessed, pretty people, give them a load of drink and hope they end up doing something they'll regret when they sober up).

With the producers attempting to engineer conflict, the general increase in BB's popularity and an increase in the amount of people who have internet access it's no wonder that most of the forums are filled with vitriol and insults, not only directed at the housemates but at other forum users. And this leads to housemates getting crappy treatment back out in the real world.

In saying all that though, I totally get a sadistic pleasure from watching one of my less favoured housemates getting booed on their eviction. But even that has lost some of its shine in recent years cos it seems that just about everyone gets booed now.
