Agree with Tob Queen. This seems to be more of a bug than anything. Ironman should not be able to come back and loot up their items after death (if the pker doesn't pick up their items first).
The solution here should have been a patch to prevent the items from showing up again on ironman accounts. Wiping the pk drops of ironmen, group ironmen, elite ironmen, and especially REALISM out of the game was not the correct fix. Realism players are not ironmen and this update should never have been applied to our game mode. Currently, when I risk a realism AGS (which is worth ~3x a normie AGS) and pk someone for an AGS, I get this junk loot. I should at the very least be able to loot up the AGS on my normie account like on OSRS. Just keepin' it real.
No support. When you were able to do this before a lot of the Ironman pkers would not even get the loot and the person they could could come back and pick it up and most of the time they were ironmen. This was put into place to stop ironmen who had died to be able to come back and pick up the items they had just lost.
