Well, in short, an edited post on a Steem frontend doesn't scrub my content from the Steem blockchain as these blocks were already signed and stored on witness servers running the agreed version of the Steem chain.
For example:
- Removed my content from https://steempeak.com/life/@soyrosa/doggie-a-short-story
- But that URL posted in this tool that helps us dig up info from the blockchain shows the full post including each and every edit I made after the first post
- Then there's also other tools like the block explorers we can use to find all this data because all of it is still there.
Until the last witness turns off their node our content will 'live' on Steem/Hive blockchains, even if we remove the content from their frontends which is only a method to display the blockchain data in the end.
EDIT: Ah, Scribe was actually already moved to work for the Hive blockchain I realize now, but the idea remains the same :-)
