In all fairness, I don't blame Frankie at all. He is what he always claimed he was, a typical girl crazy drinking, party loving type of kid- which teen isn't given the opportunity? It must have been a dream come true for him, all these girls suddenly throwing themselves at him.
XFactor themselves are the ones, if anyone should be held accountable, they took him on knowing what he was like, i'm wiling to bet they saw a future Robbie Williams type of guy in him, but it backfired on them.
