Well, they certainly wouldn't be extradited, since extradition in most of the world requires the crime they are found guilty of to also be a crime in the country of residence. I don't even think the asses who posted the video committed a crime here, let alone the guy who runs the website.
They took him before a public prosecutor for a deposition. It doesn't say he was charged, but it sounds like he was detained. May "arrested" was too strong, but it certainly wasn't something that could be laughed off.
