By the definition I gave - what you described is not art because it's an image, made without application of skill, which is then given meaning by the author after it was created, I.E it was not made with a developed idea in mind. Any meaning it may have is not apparent, or is not symbolically held by any components of the image, and the image itself lacks harmony - therefore is hard to comprehend.
Yes, exactly like Duchamp's Fountain, which was meaning ascribed to a random object after the fact. It calls out to the viewer to observe the mundane in a different way, to reassess their assumptions and view things from a different angle. It is indisputably art, no matter how it began.
You specifically worded it as "Fucked up", this means that the disorder in said photo was not intentional, it's a mistake. And the person simply lies to somehow cover up said mistake. Any implied "thoughtfulness" is mental masturbation, an attempt to reasonably interpret that which was not reasonably designed.
Even lying is expression, and doing so with artistic intent would still be art. Duchamp was "lying" when he presented the urinal as his art, because it was not anything he made, demonstrating no particular skill. He barely had a hand in it at all, just a signature which was also not his own. It was still an important piece of expression, which made it art.
But no lie is even necessary here; the person who ruined their photo could've had a genuine epiphany that the photo still expressed something interesting, and wanted to share that same thought with others. Which again, is still art. You can present something broken or cracked as art, prompting the viewer to consider whether it's really useless in that state or merely changed to a different state which is beautiful in its own way.
Again, you're not arguing with me, you're arguing with a century of consensus that considers such things to be art.
You refused to answer any of my questions about how you could possibly delineate between some artist's own works, claiming that some are art and others are not, due to not meeting some arbitrary application of excellence in their craft, which you yourself cannot define. You're the one advocating for this absurd definition, and it's a poor one that fails to offer any concrete metric for judging this arbitrary "excellence." Someone else could say "no, you're wrong, those two pieces ARE art and this other one which you claimed is art is actually not," and you would have no defense against this.
The existing definition (not "my" definition, THE definition) works under all circumstances. Anything which someone claims to be their art, IS art. There is no basis to deny them this. You can criticize it all you like, say they're scamming people, or a bad artist, but they still made art.
