Steem is not anymore a Blockchain!
Despite all my memes about Steem, I'm really sorry for this!!
Update
Changes in code (still unknown) according to the Top20 Steem Witnesses, is to 'limiting the account community321 for transfer, as the community does not have the control over this account anymore."
