I don't see how it is different from it being posted anywhere else on the internet. I.e. yesterday i embedded an innocuous message into Bitcoin's blockchain. Can you see it? I doubt it, unless you are willing to go through and decode some hundreds of thousands of recent transactions. For anyone to notice, i'll have to post a link - https://bitaps.com/97804baa2ce19454c61eeda3de1bb99fc6b005f8aa397d0b84c500f97b4ab2f2 https://bitaps.com/97804baa2ce19454c61eeda3de1bb99fc6b005f8a... Conceptually, it's the same as posting a link like dg251kctuhnoj3f4.onion/timmy_suffers_part_1.avi - unless you are actively looking for the bad bytes or have a link sent to you, you are unlikely to find them. Thus, no need for forks or any extra drastic actions.
