Kevin, cyberbullying is a real thing. People that say it isn't usually retort to "just get off your computer". When you do that, you've officially been bullied off of your computer

"oh no, someone is slandering my name" So what? If it isn't true then they have no proof which means you don't need to worry about anything.
