That has nothing to do with moving vertices or bad modelling and everything with model changes that cause rearrangements in the smoothing groups.
All you need to do is to go into sub-object mode, select all polygons and hit the automatic smoothing again. It will re-compute the smoothing of the model based upon it new topology.
If after that you still have dark areas, then there is indeed a modelling problem, mostly caused by an inversed face or an internal additional face. The last ones are hard to spot and are usually caused by incorrect extrusions of edges.
