Can you spot the professional troll?

In this game, called Spot the Troll, you are presented with screenshots of 8 different people's tweets or Facebook posts and then you have to guess whether or not the person is a troll. I got a score of 5/8

Each of the following 8 profiles include a brief selection of posts from a single social media account. You decide if each is an authentic account or a professional troll. After each profile, you'll review the signs that can help you determine if it's a troll or not.
