But let us find out. How do you define spam, and why should anyone take that definition seriously?
My definition of spam is when someone doesn't transact because they want to make an economic transaction, but rather to do something else, like filling blocks with crap or bloating the blockchain.
Alex, have you ever written any code? It's a wonderful thing to try, even if you never plan to do it for fun or profit. It's, in a way of speaking, explaining complex things to a machine, a machine which, though capable of being quick and consistent, doesn't know its ass from its elbow without you telling it, procedurally, how to do it. Step by step.
This will prepare you for future interhuman interactions, like the one I'm having with you.
Bitcoin is not sentient, it makes no value judgements beyond truth values of variable, so telling Bitcoin "spam is the stuff we don't want, get rid of it" will only result in "Brrp! bleep bloop X=42."
Please tell me you understand, and that I don't need to resort to lower, register-level explanations.
blah-blah-blah... There is no need to programmatically define spam. 'It's the economy, stupid!'
