I would need more detail than this. Are you saying he is taking posts from a year ago and posting them as if it was happening today?

Or are you saying he is posting the same exact article on Hive then putting it on Steem?

I've long said this, everyone should cross post onto Steem and sell their Steem rewards as soon as they get them and buy Hive. That makes Steem go down and Hive go up.
