Authorisation is now a bid-bot. You can send sbd only to authorisation with a post link in the memo. Before you send though, just check you're not on the blacklist – it's updated regularly. If you want to contact us, we're available on steemit chat @missioncontrol.
Parameters: min-bid: 0.001SBD, max-bid: 0.002SBD, refund blacklisted users: false, refunds (for those not on the blacklist): true – but they're done manually.
