Raccoonerr. It's people like you that give young gamers a bad name, acting childish and moronic doesn't go without punishment or at least you'll get a dent in your reputation. Your age isn't an excuse for your behavior nor can you say "It was just a prank!" As this leads to making you look like an even bigger imbecile.
Instead of just making some weak statement to hide from your mistake, just open up to your mistake and maybe if you don't make those same mistakes in the future you may earn a little bit of respect.........
Though not now of course, you can't be saved now as you've had enough time to try and learn from your mistakes. Now because of your actions you've just tainted your imagine for years to come.
