I was bored, and you replied to one of my comments so I did some random high-intelligence "Batman" sh*t on your profile:
You hid the year you were born in, but the other details are shown...
You were 13 in your admin app,
After doing the math, I found the year you were born in. (Not revealing it due to you wanting to keep it hidden in the first place)
However, you could've just made up a random birth date
