So various posts, such as [What can I do if I'm the victim of serial downvoting?](https://meta.stackexchange.com/questions/28756/serial-downvoting-victim) suggest that there is a script that detects serial downvoting.

Over the course of a few minutes, 36 of my questions and answers were downvoted (and it seems that the process is still going on)

How many downvotes are needed to trigger the serial downvoting logic?
