Most ISPs use the "Internet Watch Foundation" blacklist. I'm not convinced that there was any real risk of Tumblr being added to it en masse.

(I believe there was an incident a few years ago where an image of an Iron Maiden album cover on wikipedia got flagged, though)

NOTE: The image is on the article above the fold.

> On 5 December 2008, the Internet Watch Foundation (IWF), a British watchdog group, blacklisted content on the English Wikipedia related to Scorpions' 1976 studio album Virgin Killer, due to the presence of its controversial cover artwork, depicting a young girl posing nude, with a faux glass shatter obscuring her genitalia. The image was deemed to be "potentially illegal content" under English law which forbids the possession or creation of indecent photographs of children. The IWF's blacklist are used in web filtering systems such as Cleanfeed.

You can see from my note how much long-term effect this had on Wikipedia.

The block on that page was for four days. Of course that had no impact on WP.

You mean: "Most ISPs in the UK".

That is very different from "most ISPs in Europe" or "most ISPs".

I would very be surprised if most eu isps used a secret blacklist (contents not publushed) maintained abroad and legit communities/platforms like tumblr could just be banned out of the blue. Would it even be legal?
