This Tumblr is shaming Philly’s unshoveled sidewalks

Unshoveled sidewalk? Get it together — or this Tumblr might shame you.
(According to the city code*, property owners are on the hook for shoveling, FYI: “The owner and the occupier of any private property shall keep the abutting sidewalk free of any litter, snow, or other obstructions, pursuant to Sections 10-704, 10-714 and 10-720.”)
See the Tumblr
And you can report those unshoveled sidewalks to @unshoveled.
We reached out to the person behind the Tumblr, but the person would not reveal herself/himself.
Could someone create one for sidewalks blocked with construction and scaffolding, please?
*(Also, no spitting whatsoever.)
