These can be viewed at https://bitcoinstrings.com/blk00052.txt[] and are mostly commented on the "Wikileaks cablegate data" section of <Hidden surprises in the Bitcoin blockchain by Ken Shirriff (2014)>.

Soon after block 229991 uploaded the <Satoshi uploader>, several interesting files were added to the blockchain using the uploader, and notably some containing content that might be <illegal> in certain <countries>, as a test to see if this type of content would make the Bitcoin blockchain illegal or not:

  \Q[http://en.wikipedia.org/wiki/Illegal_prime]
  followed presumably by one such prime starting with:

The announced filename is `cablegate-201012041811.7z`. As mentioned in <Hidden surprises in the Bitcoin blockchain by Ken Shirriff (2014)>, it has an ASCII list of several other transactions, which presumably when downloaded with the <Satoshi uploader> can concatenated lead to the full 7z file. Also as mentioned by Ken, it is infinitely easier for the average user to just access the cables directly on <WikiLeaks> :-) The data is preceded by the message:
  ``

These can be viewed at: https://bitcoinstrings.com/blk00052.txt[]. Not reproduced here because we are cowards.

So basically, this was the first obviously illegal block attempt.

None of this content is particularly eye-popping for <Ciro Santilli>'s slightly crazy <freedom of speech> standards, and as of 2021, the Bitcoin blockchain likely hasn't become illegal anywhere yet due to freedom of speech concerns.

Furthermore, it is likely much easier to find much worse illegal content by browsing any <uncensored Onion service search engine> for 2 minutes.

<Ciro Santilli> estimates that perhaps the uploader didn't upload <child pornography>, which is basically the apex of illegality of this era, because they were afraid that their identities would one day be found.
