Hi Hive account@biophil
Can you confirm something for me.
The confirmer sends a confirmation comment but the pending confirmation stays in the DB until the comment is actually found inside the blockchain. That means if the RPC are delayed, the confirmer will re-attempt to send another confirmation comment because it is still returned by get_next_confirmation() call. But that is OK because you are using a custom permlink so steem should not allow you to create another comment with the same permlink. Am I right?
