No, you're actually wrong:
1. I am studying and meanwhile making money with web development.
2. I still think that you can't be mature if you 'work' on a Minecraft server lol. Imagine an admin is dating a girl and she asks what his job is. Imagine him answering that he works on a Minecraft server.
3. I don't think you are old enogh to take part in this conversation because the way you write indicates that you can't be older than 13, (and I don't wanna talk to kids).
4. I don't make fun of people that work at McDonald's or Walmart, and I have special respect for garbagemen, that job isn't easy or very fun, unlike your life as a kid, in which mommy feeds you.
5. I do these kind of threats because of entertainment purposes, and I do this with a friend. I can make another account if necessary, and this forums account isn't linked to any Minecraft account as I've sold mine.
Boom.
