i'm assuming you're genuinely ignorant about this:
if you open the babyjak{NUMBER} images in something like gimp and do edge detection, a link to CP exists in the top left hand corner. It's a way of distributing CP that was used by spammers on soyjak.party. I would suggest removing these images from your computer.
If this is intentional, I will be reporting every instance of this to NCMEC.
