I’ve seen it repeatedly.
At first I assumed it was someone grieving over, and longing for, a lost loved one, and went a little “internet crazy.” That’s the vibe I got from the posts; like it’s a shrine, memorial, outlet or something.
I’m not sure anymore, especially with how random the images tend to be.
I don’t mind its presence, though. It feels “old internet weird.”
EDIT: And I’ve never seen anyone else bring it up. TBH I thought I was the only one who noticed.
