The posting account on VS, User ID: 56814920, has 133 active ads going! So it's a big operation by the looks of things. (I usually check out the posting ID at the top of the VS ad to see how many ads they have going. Sometimes it's funny as there is often the picture of the same girl working in multiple places) 😎
This indicates to me if it's an operation or independent. No real rule to go by, just an indicator.
