According to google plus, your name is Luc Jansen, where the last name is fake, which really doesn't help. I guess I could send you an email with an image sent from a server, which then reads you ip adress out of the request, but i guess you have html embedded images disabled in all your email accounts. There is some photos of you on G+, but then you only share them with some of your friends, which means I'd need to find a less computer savy friend of yours and see whether I can acess his account. Depending on how many, and what kind of photos there are, I might be able to narrow down roughly where you live and how you look or where you go to school (you're 19, so that's kinda hit or miss). You don't look like a picture person from your twitter though. So there'd be multiple avenues for SE. I'm pretty sure Authorities could find you quite easily given only that link.
Given first name and birth date (from age down to seconds), any authorities worth their salt can find him in a minute.
edit: well, unless he was not born in a territory under the authority of the authorities in question, and is an undocumented resident of the territory in question...
