Should I be closing shops?

It is often easier for them to just roll back to the last state. The problem is EVERYTHING that implies.

This X 1000

This is pretty much a lose/lose situation, theres nothing nexon can do that won't anger SOMEONE; I'd personally prefer if we don't have a rollback, since not only does it screw over everyones progress with leveling, events, etc (especially after we just had two 2x events in a row)

But what about people who cubed and had good results? Rollbacks are a pretty devastating thing when it comes to legit progress.

On the other hand if you don't do a rollback, and just remove the duped items, people lose money, items they may have bought (though in SOME cases this is their own fault for buying things that are obviously duped) etc
