Site "The Jab Archives" (TJA, https://www.jabarchives.com/), which hosts furry porn artists primarily, has no relation to the Jab who draws loli/shota and his "Jab Archives". TJA exists since 1995, and warning about it being unrelated to the Jab was posted on their main page openly back then.
Yes, they know about each other - at least indirectly. No, I have no idea why they have the same name. Maybe this whole shebang is related to just acquiring domain "JabArchives" and rolling with it, or some other asinine reason. Or, since TJA seems to be hosting PalComix now, maybe it's something in the vein of former hosting legacy registration, or something.
Regardless, whatever - the main point is that there are no the Jab pictures in this folio. Artists listed on page 1.
