Ok. It looks like someone just did a driveby and downvoted every single entry in this subthread by 1 (I noticed because I saw my karma drop by 13 points with about 5 minute span since my last click on a LW page, and then glancing through saw that a lot of entries in this thread (including many that are not mine) had a lower karma than they had been when I last looked at the thread this morning, with many comments at 0 now at -1). Can the person who did this please explain their logic?
