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

Your choice of hostility as a strategy is noted: but how do you measure the effectiveness of the strategy? At what point do you cede that perhaps a different approach is necessary?

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.
