When you rant against a #narcissist or some narcissists' cause on social media and tag said narcissist, you might be getting a good dig in but you are definitely contributing to the problem to some degree.
I propose #antitags, where we prefix the text with a "not" (!) e.g. "#!trump"
If you reeally hate #!trump consider that he loves a good tagging.
It's an imperfect fix for obvious reasons, but hey, let's at least bifurcate the nonsense!
