I agree to an extent but this is obviously not AI and nothing about it even says as much except for maybe a bit of motion blur.

I post a lot. I regularly get these comments accusing a post of mine of being AI.

None of them have been correct.

It's gotten to the point for me that if I see someone accusing something of being AI without solid reasoning that they're pointing to? Well I just think they're completely incapable of critical thought. So far I've been right.

The enhancement you describe I believe is image compression artifacts

I agree that something looks off about the image, and it’s definitely enhanced in some way,

But it isn't. That's what is completely baffling about these accusations. They're often made from a misunderstanding of the source material and an assumption that it must then be edited in some regard.

It isn't touched up. This is just a flat image of a baby seal. Seal skin has a weird quality to it that makes it look slightly blurry and incredibly soft. I would know considering they sell seal pelts at the grocery store here where I'm from. Combine that with a touch of motion blur from the seal moving and at first look it might look odd but taking a closer look that disappears. Even the eyes one might go "Bit cartoony" but then you zoom in and realize the blue is reflection from the scrubs everyone has around them.

This is simply just a picture. No editing was done. I weep for humanity when we're incapable of saying "I don't know" or "I wonder why" and just default to "it is definitely enhanced".
