Not as easy as all that; not if you want to do it *right*.
That would require finding out who their advertisers are, and informing *them* that you are going to boycott *them* as long as they continue advertising there.
If you don't read his shit, he couldn't care less: You didn't before either; and more importantly, you didn't *generate any click-through revenue* before either -- so he's not losing a single millionth of a cent from you just not *reading* him. (On the contrary, that's a fraction of a zillionth of a cent of *savings* for him, the bandwidth that you aren't using.)
But scaring off his advertisers, that *may* hit him where it hurts: In the wallet.
