Is there an automatic downvote spree detection on SuperUser? I just got a notification that I've gotten downvotes on my answers and quite interestingly they're all at the same time period and for different questions. I assume it's a single person trying to make me feel bad, for whatever reason.
-2 12 hours ago downvote Switching boot disk, have mirrored drives
-2 12 hours ago downvote Why did Windows 8.1 damage the security permissions on a drive from another Windows installation
-2 12 hours ago downvote Computer stuck someone between QWERTY and Dvorak
-2 12 hours ago downvote Can a TV decode audio passed to it from a HDMI port?
-2 12 hours ago downvote What purpose does a modem serve?
-2 12 hours ago downvote Are subnets always contiguous 1s?
There is also one question on SO downvoted at the same time.
Also the interesting thing is that I've been on SU and SO today several times, but only now suddenly these show and it says they happened already 12h ago. Is there some kind of a delay for showing them?
