What are some issues you should consider when using online social media sites?

Some of the issues you should consider when using social media sites are lack of privacy,  susceptibility to bullying and uncomfortable minor to major harassment. using social media is comparable to screaming to the world the first thing you learn in coding "Hello World". While this may sound horrible to some it's necessarily always so bad, there are companies and firewalls put in place to protect you and your data. The slight lack of privacy shouldn't be the main turn off from social media and the good that can be done with social media. While harassment and susceptibility to bullying are also a problem, this is something that we face in real life also, except it has moved to our handheld devices.
