As frustrating as it is; people aren't receptive to the idea that maybe the three of them, due to hanging out with each other, just don't like the same people. Marcus, Halfwit, Siavash etc are naturally going to nominate similar people too; because people nominate those who they aren't friends with. To be honest, it's a statistical anomaly that they've nominated the same for four weeks running; Noirin's nominations for four weeks running were the people who ended up being up for eviction those weeks. It's frustrating to watch, I also think they've been very sly about it by just heavily hinting who they really really dislike, and are doing everything but breaking the rule. The housemates all have to give a reason for why they're choosing who they're choosing, and they can't just say 'because ___ is going to', so clearly BB is accepting these nominations as valid.
