Well isn't this cute

[Sir_Die_alot]

Arrunique the Lurker Lounge is a "legit" diablo 2 site. Meaning no dupes no hacks ect. ect. ect. As if his FAQ questions 12 and 13 didn't say enough

. 12: How do I know that these items are legit and won't be deleted by The Scan?

Items with the '  ' are known to be legit items. Items without the '  ' are known to be dupes (not legit), and prices reflect this. We make this distinction so you can take the appropriate steps to protect those items that require it. For the most part, only some Jewels and Runes are not legit. Luckily, when a Jewel or Rune is put into a socket it becomes legit. If you're worried about losing your duped Rune or Jewel, use it in something. Carrying a duped Rune or Jewel around with you from game to game is a good way to get it deleted.
 
Q. 13: How can I protect my duped items from The Scan?

#1. Don't carry duped items around with you from game to game. Keep them on a character you don't often use until you're ready to use it.
#2. Trade-Cancel immediately before you leave every game. Opening a tradescreen with another player and closing it will remove deletion flags from your items. Deletion flags may be reapplied to your item if you do not leave immediately after doing this.
#3. If your duped item is a Rune or Jewel, simply put it in a socket. It will be forever permanent whether it's duped or not.
#4. Read the Duped Items Guide.

you can scroll through his inventory and see many obviously duped items.

But wait! That's not all he has a guide to avoid dupe deletion. Excuse me while I vomit.
