Oh yeah, the circle-jerks.... The likes of @adsactly, @exyle and friends. The ones who actually 10x/day themselves through voting their cronies. Those are the worst. Ironically, the traditional abuser @exyle runs a witness. You would think that someone who runs a witness would know better but obviously that is not the case.

I'm in the same camp as you when it comes to self-voting comments I only do it for visibility and very rarely. Recently I stopped self-voting my content altogether although before I was at around 5-10%.
