Ladies and gentlemen, it seems a new exploit has just entered the building.

This whole thing is especially dangerous simply because its basically untraceable once things change hands enough times. Someone could put 3 or even 4 stars on any piece and no one would know it wasn't just a lucky scrolling. The danger to the game is not simply the +37 or +49 or +72 stars equips, those will get removed eventually, its the godly equips that no one would dare risk enhancing 4 or 5 times, that now can get 4 stars without a major risk.
Anyone can take a look in the scania FM and see the catastrophic results of this exploit. There are tons of pieces of gear in almost every FM with at least 4 stars on them. This is game changing.

I'm going to avoid anything with stars for now just in case.

This is exactly what I was thinking. The hack works in a way that you're not actually altering the item, you're just tricking the item. There's no real way to track it. The obviously hacked ones will get deleted, but ones that still have a chance of existing but being pretty damn lucky (like one that had only 7-9 scrolls passed) might stay i9n the game, even if they weren't legitimately made. I expect a log of smart people to make such items before moving on to make impossible items. That way, even when this is patched over, they still get to keep a godly item.

Not that Nexon cares that much anyway. I wouldn't be surprised if they know this is going on but are dismissing it as "just some lucky people" because they know jack squat about the game.
