Sounds like scaremongering to me, what are they saying on that forum?
I am not aware of anywhere on Lombok that can really be described as dangerous though I do find the behaviour on the roads quite alarming at times.
Wandering about on the top of Mount Rinjani is also a bit dangerous as the ground can be a bit slippery, especially if wet.
If you want some accommodation recommendations then please give a daily accommodation budget guideline as there is a range of options on the island from very basic rooms, pleasant homestays, boutique resort hotels through to full 5 star resort standards.
The last time I went to the southern coast it felt pretty normal and I would not discourage you from staying there or visiting as there is some very pretty coastline and beaches in the south.
If may feel like a bit of a "last frontier" as places like south Lombok are getting harder to find in recent years.
It does remain quite undeveloped and most of the southern coastline has little or no built up tourist facilities of any kind.
If you are feeling uncomfortable with the idea then stay on the mid west coast at or near Senggigi, or on the Gili islands in the north west region of the island. There are more people around there and it is more developed, or at least parts of it are.
If you want to be in the south but are maybe seeking a resort type experience then have a look at the Kuta Lombok Novotel, otherwise there are a number of options at Kuta Beach and it has cafes, warungs and restaurants.
It all depends a bit upon your budget and requirements.
