Can online trolling really be stopped ?

The concept of being anonymous while surfing the internet has been taken for granted. The purpose for social media and any other sort of online website was to show people and appreciate ones experiences; however, their are very few people who went the extra step and decided to cause drama in people's lives. Having trolls in your comments can disturb people causing them to react and comment back to them. Sadly, that is what some trolls want from people, all they want is for people to have negative reactions. Sometimes these reactions motivate trolls to keep trolling people and cause chaos. Other times trolls want to cause emotional stress to people and if there is no reaction that doesn't phase them to stop. In a way these trolls find this hilarious and will continue to emotional harm to people. So how does one really stop these trolls from continuing to troll people? People would say just ignore their comments and continue on with your day , or don't pay attention to what they are saying because no matter what it is not true. That's not the deal, for certain people this is too difficult. A troll will hit certain peoples buttons just the right way and make sure they get the reaction they want.
