Tblogging-15968here is no such thing as an innocent bystander and if you have seen someone being cyber bullied online, you can report it to the online site or app. Ignoring it may feel like the easiest thing to do but the person who is being subjected to that bullying may need your help and support to get it stopped. Most sites now have a report button which is something you can do and this will send the bullying comments to the site to investigate.
