Internet Trolls

When the word troll comes to mind, I immediately think of someone who does things for the sole purpose of sabotaging or aggravating another person. An internet troll is someone who says things online to ruin something or someone's post. I think that online trolling is a waste of time for anyone, and that people only do this to make themselves feel better about themselves by putting others down. Anonymous trolling is not okay, and there are so many cases of it on twitter, Instagram, and other forms of social media. I do not understand why someone would post a derisive comment just for fun, so they can watch everyone argue on somebody else's post. It just doesn't seem right. Anonymous trolling on the internet is wrong, and sometimes it can get out of control.
