Most probably everyone knows, that Hive is almost an exact copy of Steem blockchain (at least it was yesterday when it came alive). It means all of your assets in your wallet is exactly the same.
If you delegated some SP on Steemit and the delegation was active at the moment of the copy, that delegation is still active here, on Hive chain.
But some of us don't want to do exactly the same, what we did on Steemit, do we? This is the easiest way to undelegate and get back your HP:
Just replace YOURACCOUNT (delegator) and OTHERACCOUNT (delegatee) in the code above, copy and paste it in your browser and sign it with Hivesigner using your active key.
You can check the result on Hiveblocks.
Enjoy your fresh start! 😉
