Firstly, thanks for the civilized answer. Here is my counterpoint: Because the spammers go around a back door we just make it easier for them opening OP_Return? It’s a flawed argument. Why don’t you work on closing the back doors? And frankly, I don’t care about miner’s profits. I’m running Knots and a solo miner. Just as Satoshi-San intended. Pure and simple. #Bitcoin is Money. Nothing more nothing less.
