Three threats in two days to three of our universities.
The first one at Otago University was made on an internet message board called "4chan" where users can chat and post messages anonymously.
It's the rebel website of the internet and one step removed from the dark web.
Posts are all done without anyone finding out who you are.
The threat to the university may have been empty but it was made in a public forum and police are taking it seriously.
But catching someone using 4chan is hard. The anonymity factor makes it very hard to authorities to trace users and police are trying to control something that seems uncontrollable.
