Hacked Items

I'm saying it clear...I said...YOU know that item was MADE by a HACKER and you BUY that item.

You know, there's a reason why everyone comes up with these scenarios, and it's not just to make their paragraphs long and convoluted. Yes, buying illegit items from a known hacker is illegit. But the ramifications that stand in your way are:

1. No one would know except the buyers and sellers themselves, at most, so it wouldn't make a difference, unless someone came right out and admitted it.
2a. The buyer is not obligated to inform themselves about all the hackers in their server.
2b. Hackers don't go out of their way to broadcast that they are; also, they may actively hide under legit-looking IGNs and legit-looking equip (the example about the 350 10%/30%ed equips).
3. Sometimes it's just unclear. Ex. a mushroom shop filled with ilbis at 500k under market price. It could be a hacker. But it also could be a merchant or just a hoard from someone wishing to upgrade to cilbis or furies.

Given these constraints, whether you are "legit" in buying an item only really matters to yourself. It is the perfect crime.
