Looks like they are back on October 24 2014:
-2 06:37 DV (Q) If Voldemort had succeeded in killing Harry Potter, ...?
-2 06:35 DV (Q) Has anyone other than Sybill Trelawney made a real prediction?
These fit the usual pattern described in other blog posts:
- Question from 2012, with no fresh edits and no prior DVs
- Question from Sep 23 2014. It had 8/-1 before then and no fresh updates
- Question from Sep 11, 2014. It had 14/0 before and no fresh updates
As usual, one of the downvoted questions was uber-old and had no connection (by tag or time) to the other ones....
AND, that August 2012 question was among my only 2 questions from that period in 2012 that were not already downvoted.
