Rather than giving a subjective answer -

It contains a SynthID watermark.

• There is no lock on the bathroom door.
• The shadows don't match the light fixture's position
• No reflection of the photographer in the metal finish on the hygiene disposal bin.
• Wall starts turning into an alcove in the upper right corner.
• The toilet's height leaves no room for the sitter on the shitter.
• It's a public toilet only accessible by rock-climbing. If it were real, it would be at an art museum and therefore findable with a search engine, with the name of an artist and the name of the museum where it's displayed.

The tiles have completely random sizes

This is some Escher style BS:

This makes no sense:

The toilets with the ceramic bottom exist to hide the pipes in the bowl. It makes no sense to keep that if it’s not attached to the bottom.

It makes sense for an AI because that’s probably 80% of their training data.

When someone posts slop on Lemmy, I give them an “AI” user tag. It becomes that much easier to identify in the future if I don’t block them. But it also tells me who to block when I keep seeing slop.
