Pauline - Would have been evicted regardless of being PHM. Just not a very nice person.
Chris - Wasn't particularly liked by the Helen crowd prior to being PHM anyway, so most likely would have still faced eviction every time that he has.
Toya - Was evicted that week due to a twist involved with being the PHM, but she was disliked both in an outside of the house by that point anyway. As soon as she was up she was a goner, whether she had been a PHM or not.
Matthew, Jale and Danielle - All evicted because of reasons that had absolutely nothing to do with being a PHM.
Also, let's not forget Kim and Helen were PHMs too. Helen is still there, and if Kim hadn't walked Danielle would still be there too. So Chris is not the only one that's survived this supposed "curse" of being the PHM.
