And... they are back

Since I have significantly slowed down my participation on the site (in part, due to emotional fatigue cause by the targeted mass downvoting), the mystery bulk downvoter(s) have stopped... 

Looks like they are back on October 24 2014:
-2 06:36 DV (Q) Why didn't John Connor give a good cover story to Kyle Reese?
-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.
