Hasn't the "you don't pay $15/month" argument been exhausted to death and the verdict is that subscribing to a private server is the equivalent to paying for a retail server?
If it wasn't for players playing on this "free" server, they'd have nothing. Nevermind the fact that they get donations behind the curtains and the like, so please don't use that argument.
Translation of this person's thread: "I want to add an extremely cliche post with nothing relevant to add. Let me waste your time!"
