xRin is considered a troll by many, and probably is. However, people still enjoy messing with him. He was mass party trolled many times, and told to get out more than that. He made multiple threads saying that he would leave if the thread got a certain amount of posts or views, but he never did leave.
He was most likely known as a troll for spamming threads about PewDiePie and other YouTubers that most of OT hates.
As in a private chat with mathkid421, he is turkish
