You can backup any content here, just set the rewards to burn since it's been published over there first.
Any authors you want to bring here, because only the keyholder controls their content here, can find support now, we have places that will welcome them, now.

Not your keys, not your content.

And, welcome back.

It will post to the chain and rewards will be paid out, presuming the crowd doesn't boo the content.
