Anyone with any brains would claim the deed and re-deed thus changing the item ID.
You're still flagged. The moment the duplicate items are created they get flagged.
I used to do the same thing with gold checks. Dupe 124 Gold checks with beetle dupe, Recycle them with vendor house and bank on same node. Safety then was that if the duplicated items crossed a server line that they would be deleted, which is why character xfers were changed so that when you initiate one you are changed to a different server like jumping a server line (aka what ea calls the "warehouse") so that any duped items are automatically deleted. However ea implemented a non-intrusive flagging system for duped items. The moment that two duplicate IDs are created on server they get flagged, normally it would be easiest to have them deleted right there (which they can implement) but I think that instead of doing that they recognized if they just had their GMs tend to the flagged people and watch, they would be able to not only remove the items and ban the players but also witness first hand how the dupe is performed and assess a method to fix it.
Think back like a year ago or something, there were a couple server roll backs and atl was mysteriously brought down for "extended maintenance" after "a bug was found post patch". My theory is that was when they implemented that flagging system, and they were suddenly introduced the reality of just how severe the problem was, resulting in a panic on their part to roll back and extend server maintenance as a means to dealing with the issue.
Most of this info though is just conjecture and theory on mine and friend's/associate's parts from watching the spike in duping bans. In the 33 people that I know who have been banned for duping in the last 8 months, 11 of them have been doing it (With different methods over the years) since Pre-AoS, four of them together. All except a few greedy guinea pigs, were experienced, recycled items that were able to be recycled and most used proxies.
Like I said, I wouldn't touch anything dupe related at all. Anyone with any brains would stay away from it :>
