I was wondering the same thing. Not a peep on Jamie Reid or longtime vegetarian Bob Barker, who croaked at 99—a living refutation of the fatuous "you need meat to be healthy" brigade.
Morrissey Central was a month late on the passing of Murray Melvyn, but that was a single oversight during a time when other memorials were still being posted. I agree with you that it's probably Morrissey himself who's posting these. (Interestingly, the Murray Melvyn mistake was rectified on the same day someone on here brought it up). I also think it was Morrissey who posted the "AI Lana Del Rey sings the Smiths" videos.
