This question already has an answer here:
For people who are trying to close this: Its Serial negative group voting..
I am aware of automatic detection script but looks like it fails in such scenarios.
Many times I was a victim of serial downvoting. But SO is pretty awesome to detect and revert it
But looks like now a days downvoter have become more awesome,I am facing short number of sudden negative votes. And looks like same person with multiple profiles is doing this
I am not saying I am too genius to receive downvotes but
1. The questions are almost 2 year old and never received any downvote before.
2. All of a sudden in 3 mins how can 3 or more random people downvoted on my old questions? (Looks a very low probability case)
I am not afraid of downvotes but just hate when someone gives it without any reason.
Do SO take any action against such things?
Looks like even the downvoter is reading this post. Few more rewards after taking this up
Year old questions and all of a sudden downvotes.
