For 3 years, as you are possibly underaged. Your name suggests you were born in 2007, what means you will turn 10 this year. I'm leaving your wall open, so you maybe will prove me wrong about you being underaged.
For 3 days. Reason of this block is, that you have made some minorly disruptive edits, renamed a page without informing the community, pointing out staff member's grammar after being informed about page renaming, arguing and incivility. I am leaving your message wall open to you due to policy saying, that first block can't have it locked to the blocked.
