Liar Tree Sap 100%

How would you know that they were legit white scrolls? The point is that you don't and you can't, because Nexon never made ID numbers attached to individual items. ALL the duped items appear the same to Nexon.

Thus, there must have been some method (such as using more than x amount of white scrolls during the period) that would allow them to distinguish (whether accurate or not) who to ban or not. It's unfortunate, but that's a risk that several people have already taken.

However, on the brighter side, since there is no method at which Nexon can distinguish who was using legit white scrolls or duped ones, they cannot issue a permanent ban.

I think we should stop with our assumptions and whatnot. How do you know how Nexon works with this? Do they log this, or do they not? How do they log it?

We don't.

Let me care to elaborate. Assuming Nexon has less than 16 million characters, we may assume the following:

• Each character would equal to a 3-byte hash
  
• Each item in-game has a 2-byte hash
  
• Arrows stack @ 1000 per = 2 byte max.
  
• An efficient way of knowing the approximate time when the the trade happened may be stored in 1 byte.
  

Now, that means Nexon needs at most 11 bytes per item transferred, if they don't want to include mesos transferred. If they do, whooy, 15 bytes instead.

Let's estimate 1 million transfers a day, which to me sound like a lot. That equals to 15 million bytes, or 14.3 MiB a day. That data amount is literally nothing in a year: A mere 5 GiB of information. That's what I'm able to get on my freaking memory stick if I .rar that piece of shi-.[*]

Now, as I totally know this is "completely" useless theory, I'll explain why:
Why is it that an equip keeps its stats even when it's dropped or traded? According to you, Nexon never had ID-numbers attached to individual items. Yet the "Tiger's Spear" keeps its name-tag. How is this parsed?

And is usable items, etc, (cash etc...) based on ID too? How do cash-items manage to know when they're supposed to expire? The fact is, most of these answers, if not all, we don't know!

And, since we don't know, none of you can go state "Hey, but since they know who's duped and bought items..." or "Hey, since they don't know who's duped or bought items..."
That's because we can't base those statements on assumptions.

 * (Yeah, I know this idea may be tweaked more)

This is based on a very "inefficient" way of storing information btw. We could eventually split the bytes into bits. That shouldn't make a change in the two character-hashes, but for all the others, that would mean:

• Two character hashes: 48 bits. 0 saved.
  
• Assuming less than 8000 items in-game: 13 bits. 3 bits saved.
  
• Arrows stack @ 1000: This may be packed into 10 bits. 6 saved.
  
• Approximate time may be even more approximate: 1 bit. 7 saved.
  
• Signed integer may be converted to unsigned: 31 bit. 1 saved.
  

That's 103 out of the former 120 bits, or approx. 15% space saved.

Keep in mind that this would require more processing-power to go through the data however
