There were a couple of posts about keeping track of trolls that popped up on GT over the past week. I've received some private questions about whether or not this is ok by site rules. Jez hasn't had an updated rules of the road post in some time and certainly not since this latest Kinja changeover. However, in the past, keeping public lists of trolls/alts/problematic commenters has been actively frowned upon and commenters who have posted similar things have been asked to desist and their posts deleted.
That said, speaking for myself and my experience as a mod, I personally don't want to see those kinds of lists posted on GT. They make me uncomfortable on a couple of levels, not in the least because some people's definition of 'troll' is just 'someone who I don't like.' It's too subjective and I think allows for too much focus on negativity.
