If it was orphaned, why did I just get BTC from it??? Will they take that back?
You haven't got confirmed BTC from it. It will be deducted from the total as soon as it is flagged as Invalid.
Rather galling, considering that our result was timed first (by one second).
You can send ghash.io your thanks on that one. Their connectivity with the majority of nodes/pools is downright malicious in how bad it is.
