{help} Does this dupe method still exist?

week ago or so someone said you can dupe by dropping an item in the guild hall and spamming the interact key over the vault/nexus portal. does this method still work? because i'm updating my ahk script and have it ready to go but nothing has been duped yet.

I think it does u just gotta try alot :L id test it but im not in the mood R.I.P 4/8 t-t

BY the way u dont have to drop in guild you have to drop on guild portal in nexus,if u drop in the guild hall and no one is standing there the item vanishes!
