FB Abs - are crunches bad for you?

I want to start the FB Abs programs, but I have read on numerous sites that crunches are bad for your spine. I've seen many of FB's abs workouts and they include many variations of crunches. Does anyone have any comment on that? I love Daniel and Kelli, but I have also read criticisim on them that they are promoting unhealthy and even harmful workout routines and they are not true professionals in this aspect.

How much of this is true? I do believe Kelli and Daniel know what they are doing, and are aware of all the stigma(?) that crunches have.. so should I trust them? Or should I be more wary? Have they commented on these claims/accusations before? Does anyone have some experience to share?

Thanks in advance, and happy working out!
