A few years ago, he did start cancelling shows due to what seemed to be health issues that put him out of action (there was a brief period of "DOOM is dead!" rumors floating around). That lead to him re-scheduling all the concerts, and then for whatever reason (persistent health issues or just lack of desire to go out on the road), I'm guessing he just said, "Fuck it, it's just me wearing a mask up there, I can get someone else to do it." Which lead to him sending out other people wearing the mask, which lead to the outrage, which I'm guessing lead to him creating this whole idea of "Doompostas."
