You guys made the blue haired girl take her videos down. I would too if someone posted mine on a site that seemed weird. I would feel stalked. Maybe she doesn't know English which would be creepier.
At least youtube/google let's you track it.

Plenty of deltas have piercings, tattoos, unnatural colored hair, etc. I know many IEE who dye their hair with a rainbow of color.

I am not sure what kind of sheltered life someone needs to live in to not notice. I know sol is not in Siberia so he recognized it is possible. I only looked for a few seconds at her video when it was posted but since she wasn't speaking English I didn't get much of an impression on type.
