They seem to be human moderators, but either unable or uninclined to stop trollish behaviour in a useful way. It has driven a lot of posters out of the forum over time – people outright said they were leaving because of the poor moderation, and those tended to be people I enjoyed discussing things with.
They seem to moderate based on the content of individual posts and not by monitoring the forum as a whole. I suspect they may value "number of posts" over "value of posts" or any actual community fostering.
