I recently had trouble using one of the services the students use to maintain online discussions. A student posted a rather inappropriate comment towards another student. A fake name was given, but I did get an IP address and blocked that user. I have contacted the ISP and unfortunately received a form letter from them saying they might check it out. I am worried that my students see online spaces as free-for-alls where anything goes. I need to work harder to show my students that they need to be responsible for their actions offline and online.
