Milling has always been an ancillary effect - something you do one or two times throughout the course of the game. Cards like Fraying Sanity prevent players from actually PLAYING the game, becoming completely antithetical to the whole ******* point.

Since you have been unable to properly manage this over the past few years, you need to completely remove ALL cards that have any "milling" effect, and ban all players who use this or any similar cards.
