Just because that Bitcoin (and English) are dynamic doesn't mean you have any power whatsoever to change them at individual level let alone "filter" out any words or transactions you don't like. In fact we all are so powerless, I don't give a flying fuck about spam, the more the merrier I want someone to pay fees to miners so I don't, but I also want covenants but I can't, because filtering out anything already possible is so extremely fuckin hard at the current scale of Bitcoin... Chances are it ossified already.
