@clevecross That's really not how blockchains work. They record anything and everything without discrimination. The NSFW tag being filtered is a Steemit Platform issue. Not a blockchain issue.

Block chains were originally designed to be 100% immutable ledgers to act as historical records for finance. They work great for banking records, but not so well if you want to go back and delete a record because they make sure the current block must rely on the previous one by design.

• Great for banks where you want 100% accuracy and consensus. Integrity of the information is priority #1.
• Bad for use cases when you would all but kill for the "Delete" button in hindsight after a post.
