Hello, I have read that once you create an account on Steemit it remains on the blockchain forever! There is no way to delete an account and no way to close them. If you edit an account or blog or comment the original information has already been saved to the blockchain and that also remains on the blockchain forever. As far as I know the steemit portal only shows the edited version and accessing original "deleted" content may be available through third party apps or if you have a better understanding of accessing the blockchain. The old line from Cheech and Chong, "this will go down on your permanent record," definitely applies here. So be careful on here and always remember - say it don't spray it, ha ha!
