If a VA has a selection of company livery freeware aircraft that are of acceptable quality complete with a 3D VC, I could be tempted. However most VA aircraft (in my experience) are old hand-me-downs of debatable quality and no VC, which (with respect) I would not touch with a barge pole when there are much better and more interesting payware aircraft available. A VA that refuses payware pireps is kinda shooting itself in the foot if it wants to grow. No disrespect but good luck!
