You wouldn't be the first. I was also just 11 years old when I made my first account, because I was too anxious to wait until my 13th birthday, and I really wanted to share my art with some of my friends from YouTube who also had accounts there. However, to quote a cheesy Dhar Mann video, I would "live to regret it", because I didn't realize people who liked to crap on young, beginner artists would even care about my old, childhood art, thinking they would just ignore it, and I ended up being bullied into giving them reactions, which eventually escalated into me deactivating my active account at the time. Of course, it didn't stop there, and I would be harassed for years, but the fires seemed to die down now. Either way, after my own experience, I actively advise minors against lying about their age to sign up for the sake of their own sanity.
To this day, people still get the chronological order of my accounts wrong; the one I'm most known for was created first, not the one I deactivated beforehand, and one of my so called "alts" which turned out to just be a coincidence in naming wasn't even mine, and it was created years before I even knew how to make an account, before I was even aware DeviantArt was a thing.
