Anyone who has ever worked on social media will know what the troll behavior is like. The trolls are the people who seem to take pleasure out of creating animosity and hatred. They will say things to provoke a reaction. And when they catch someone in their sights, they decide it's time to play.
The best advice that anyone can be given when it comes to dealing with trolls is to just ignore them. Most of the time, if you don't entertain them, they will give up and move on.
But there is a rare breed of troll who develops a vendetta—and no amount of ignoring them will make them go away. The trolls see something in you that makes them think that you're vulnerable and they attack. And they keep attacking until you finally break down.
