If they considered it slop, they would not have bought it in the first place.
Did you actually read the complaints? The “product” looks fine if you don’t look at it closely, but is unusable when you zoom in. It also presents itself as pixel art, so zooming in is the expected use.
How do you think the buyers noticed that it was AI-generated if they didn’t notice the AI disclosure? Because they downloaded it, looked at it, and noticed that it was slop.
And you do not get 500 followers for creating slop.
How many of them do you think are actual humans?
