Let's say the person did have consent. It's still illegal, but is it still wrong?

Let's say they didn't have consent. It's wrong in the sense of it being "revenge porn", but should it really be considered as child pornography in the way it's classically viewed?

It's a gray area in that regard.

If someone is uploading things to his website which he can clearly identify as child porn without further analysis (if the child depicted is under 13, it's probably pretty easy to tell, unfortunately), I don't think he should hesitate to report it to law enforcement.

And if law enforcement investigates and learns it's not actually child porn... then they almost definitely won't charge anyone so long as no other crimes were committed. There are no downsides to reporting it and many downsides to keeping it to yourself.
