Hard to say whether this is good or bad, on the one hand we have miners complaining that their transactions won't go through but on the other hand we have miners shouting "yippee" because a block was paid 13.6 BTC rather than the 12.5 BTC that you get for an empty block. I'm not even sure that it's spam, could be Coinbase users moving their stashes out of the clutches of US government.

May we live in interesting times.
