I wonder if it is fishing itself that they don’t like, or if it is the prevalence of fishing photos on dating sites. I know that a lot of guys post fishing photos on their profiles (probably because most men don’t take many photos of themselves but will take photos with a nice catch), so maybe it just seems unoriginal or low effort. I’m honestly not sure, but my only point is that it may not be the hobby itself.
I’m on mobile, so maybe the photo isn’t loading at high resolution, but I don’t think your points lead me to believe AI generated this.
The finger looks a little odd, but it could just be the way the shadows fell. The garbage can doesn’t look flat against the wall. If you look in the reflection of the mirror, one corner is closer to the wall than the other, which would account for the distortion you mentioned. The blue coat of the back of the chair might just be a coat. The chair legs seem like they should be behind his leg and the trash can. The foot pedal on a plastic trash doesn’t seem like the sturdiest thing and can just bend. The lid seems symmetrical to me personally. There just aren’t enough pixels in the image for me to see if there are buttons or not.
Maybe I’m completely wrong and it is AI, but it seems to me like too many of the fine details match up with reality. It may also be the low resolution that makes things seem more realistic. If it is a fake image, I think it would be more likely that the photo was taken out of context or staged.
