Under “Branding”, the 2nd and 3rd pictures you show appear to be skin removal scarification, where the skin is cut with a scalpel and peeled off (should have been in section 9). Branding involves flame or heated metal. Fresh Branding doesn’t look like much, just a singed mark. After a few days it changes, the dead skin falls off, and the remaining tissue usually raises somewhat in a scar as it heals. Those 2 pictures show fresh blood, exposed subcutaneous tissue where the skin was peeled away in cutting.

Also, “corneal tattooing” is probably not the best description. The cornea is the lens that covers the pupil. I’m pretty sure “Eyeball Tattooing” involves injecting pigment into the vitreous humor (the fluid filling the eyeball) but not actually piercing the cornea.
I’m fairly heavily modded myself, but this one gives me the willies. Can’t imagine risking blindness just to get a reaction =/

Anyway, well done article. I see a bit of shock factor here and there but it’s not prejudiced against modders.
