It's a normal video, I don't know what you're talking about.

That dancing anime girl is from this video, "loli god requiem" https://www.youtube.com/watch?v=Ci_zad39Uhw

It's a video of an underage-looking ("loli") anime girl insulting the viewer for being a pedophile.

At this point it's mostly used by pedophiles in a sorta tongue-in-cheek way.

Of course, all the best security professionals are either pedos, israelis, furries, or all of the above, so it's not really surprising.

it's the software engineering tradition

you new here?

Anime fans permeating throughout on the internet? Impossible. Never heard of such a thing.
