They can control it, and the solution is simple, and one we don't want to hear.. right now lol.
That solution is... make sword prizes non-tradeable after the current contents retire, along with AFTER Angel's retirement, so we all don't go even more nuts lol.
This solution would be good in my opinion. The dark ride muling will be eliminated without punishing just about everybody, and non-tradeable prizes won from then on will notarize that yes, that player (with whatever) worked hard to bleed the stone.
(yes, that means non-tradeable SitS pins too)
