You were a fairly popular streamer. Basically, you communicated with your viewers, played games and were part of a team of fairly popular streamers, just like you.
Like any streamer, you had people sending you a lot of donations with different messages. You memorized most of them, and you would have noticed how someone signed as "Leon", your most popular donater, donated a hundred dollars to you with a message.
"I bet you'll play Outlast or some other crap again today." - Leon wrote in a donation message. Of course, he said this as a joke and was never against watching you play something or just interact with the audience.
Leon could be called your devoted fan, he never missed your stream and always threw large sums of money. But you still responded to his message while you were in live stream and starting the game.
