There are very few writers here I've actually blocked – and then, only for the most egregiously hateful bigoted content. Personally, I think it's a worst insult to just unfollow, mute, and ignore them. My old grandfather used to say there are two ways to really piss someone off. One is to ignore them. The other – and, in his estimation the best way to piss them off – is the "nice them death."
Nothing pisses an asshole off more than the object of their ire being nice to them, grandpa Jack used to explain. It makes their behavior look bad even to themselves. "No one likes being proven what an asshole they are."
