a state of extreme anger and frustration caused by getting numerous unwanted or unsolicited emails ('the torrent of spam caused numerous counts of spam rage') I was looking at various sites on the internet when I came across this article about several people being arrested for making threats to companies and other people sending out spam and other unsolicited email messages.
