Thank you for your reply.
self and paid voting is not necessarily "abusive".
I agree with this. It's not necessarily abusive, but it can be. For this article, I was thinking just about the subset of that behavior that is abusive.
I also agree that the definition of the word "antisocial" is sort of slippery, but I was thinking of predatory forms of behavior that go beyond ignoring social amenities to actively harming others. The Colman & Wilson paper was a study of Anti-social personality disorder, which has a specific psychiatric definition (listed in their paper), but of course my article did have a broader focus.
