mistakenly?

This reads like some guy tripped and fell on top of his mouse and in so doing, accidentally turned on screen recording, performed the exploit a few times, got the anime girl asset and soundtrack, dropped all of them into Premiere, added the weird effects, rendered the video, and published the video to Twitter. "Ow. What did I fall on? Oh noooo, I broke the embargo!"

Heck of a mistake.

Your comment is funny. But obviously, "mistakenly" refers to the mistake of believing the embargo being broken, and then, very intentionally and not mistakenly, publishing a stupid video.

Definite candidate for the next "What Did We Get Stuck in a Twitter Video this Year?" list.

reminds me of the guy that dials in to the mullah, asking "hey, I fell on plate of shwarma and ate it, what should I do now?"

some people are just lacking coordination

That video was published 4 hours ago by lcfr_hax, the embargo ended four hours ago. Was it posted earlier and then deleted or something?
