Interesting factoid also for those reading. The blockchain of bitcoin has child porn embedded in it, and this is totally fine. So, making a forum where simultaneously, everybody can post everything they want, with zero moderation, and at the same time one can select which parts they wish to see, is absolutely trivial
It does not have to be encrypted whatsoever. Bitcoin's blockchain is not encrypted. Of course, adding encryption would be ideal in the end, as I'm sure there is also child porn embedded in monero's blockchain and we just don't know for sure but I digress

We provide the firstsystematic analysis of the benefits and threats of arbitrary blockchaincontent. Our analysis shows that certain content, e.g., illegal pornography, can render the mere possession of a blockchain illegal. Based onthese insights, we conduct a thorough quantitative and qualitative analysis of unintended content on Bitcoin’s blockchain. Although most dataoriginates from benign extensions to Bitcoin’s protocol, our analysis reveals more than 1600 files on the blockchain, over 99 % of which are textsor images. Among these files there is clearly objectionable content suchas links to child pornography, which is distributed to all Bitcoin participants. With our analysis, we thus highlight the importance for futureblockchain designs to address the possibility of unintended data insertionand protect blockchain users accordingly.
Illegal and Condemned Content. Bitcoin’s blockchain contains at least eightfiles with sexual content. While five files only show, describe, or link to mildlypornographic content, we consider the remaining three instances objectionablefor almost all jurisdictions: Two of them are backups of link lists to child pornography, containing 274 links to websites, 142 of which refer to Tor hidden services.The remaining instance is an image depicting mild nudity of a young woman.In an online forum this image is claimed to show child pornography, albeit thisclaim cannot be verified (due to ethical concerns we refrain from providing a citation). Notably, two of the explicit images were only detected by our suspicioustransaction detector, i.e., they were not inserted via known services.
The possibility to store non-financial data on cryptocurrency blockchains is bothbeneficial and threating for its users. Although controlled channels to insert nonfinancial data at small rates opens up a field of new applications such as digitalnotary services, rights management, or non-equivocation systems, objectionableor even illegal content has the potential to jeopardize a whole cryptocurrency.Although court rulings do not yet exist, legislative texts from countries suchas Germany, the UK, or the USA suggest that illegal content such as childpornography can make the blockchain illegal to possess for all users.
