Cause trolling is a actually part of a company call "InsertFakeNameHere, inc." that intends to compete with the likes of Google and Facebook in the social networking field. Their idea is to first set up camp in various social hangouts all over the internet, ruin the experience for people there, and suddenly when the world has had enough, release their own product which will be surprisingly troll fee cause they want their product to outshine all the others. They are currently in the process of creating Logos and other media to use to spread awareness of their product and you just happened to find one of their propaganda material.
All illegal and unfair, yes. But as long the company doesn't "exist" yet as they haven't declared anything, so they get to do as they please.
