Of course there's something you can do: you can enforce stricter consensus rules. But no one in the puritan camp has the conviction to do so.

I didn't put forward any conspiracy theories. Regardless of the motivations, opening mempools up to spammers by default is bad for the Bitcoin network.

Bitcoin needs to be openly hostile to spammers and scammers. A consensus change is not necessary to accomplish that.

Fork it, then. I've said multiple times here that we should be forking the fuck out of it. I'm in the puritan camp. Prove you mean it. But you don't mean it - you specifically want to attack bitcoin. You're not interested in attacking something inconsequential. Big talk, but that's it.
