Here's a screenshot where someone made a (completely uncontroversial) comment, and within 1 minute was downvoted to "dead". Looking at their history, all of their comments since yesterday have been downvoted to dead, most (but not all) of them equally uncontroversial. cannot find any other explanation besides a botnet that targets specific users for instant downvoting when they post a new comment. Perhaps I'm mistaken, but I thought it would be good to bring this up to the attention of the community.Edit: just confirmed that this wasn't a fluke, a response by that user to the thread he's involved in is again showing as dead, at 0 minutes:
