I posted two comments in response at How can octogenarians pull out a refrigerator surrounded by walls?, but I no longer see it. Why was it deleted?

I apologize, but isn't it obvious that How can I clean the back of my fridge, without pulling out the fridge? doesn't duplicate How can octogenarians pull out a refrigerator surrounded by walls? The former assumes you can't pull out the fridge, but the latter asks about pulling out a fridge.
