I'm extremely sorry to tell you this, Matthew, but unfortunately due to the federal laws in the US we aren't legally allowed to provide you service until you're 13. It's called COPPA if you want to google it to learn more.

Sadly we will have to ban your username ASAP (within the next day or two) for violation of our Terms of Service - I don't like it any more than you do. Please make sure you email me at sneak@steemit.com on your next birthday and I will see to it that your ban is reversed. We want to have you here, but we can't break any laws to do so.

I apologize for this; US federal laws don't give us any other options here.

PS: Be careful on other sites - they are subject to the same laws and will likely ban you if they find out you're under 13.
