James was making videos on YouTube about video games. Somebody else pops up and he does a similar thing (Let's just call him Christian) and he is getting tens of thousands of subscribers for what he does. James on the other hand is busting his ass out to make good content for his followers and Christian is getting more subscribers every day. Suddenly, other users point out that Christian is a cheap imitation of James and many users unsub from Christian and subscribe to James.
