Well actually that’s a lie. In cyberspace the amount of people who will hear you scream is dependent on what sort of cyberspace you are in but even if they do hear you does it matter?
Everyone has a different way of sharing opinions and dealing with problems online that range from something like this on Facebook where people you know on a personal basis have chance of seeing your posts (only 12% of your friends if this source is to be believed), using an online persona whether it be on a forum like 4chan or Reddit where you can anonymously share your opinions,experiences ect to a larger audience without repercussions or by escaping into a game such as League of Legends or World Of Warcraft you can forget about your problems from a while and just play.
I will leave you with this video, which i believe is a great example of using a cyberspace to take out frustrations. Its shows a professional league of legends player “Zionspartan” during a live stream on Twitch.tv taking out his anger from of being relegated from the LCS (A Pro league) which essentially means he is out of a job.
