Is there a possibility to get my name deleted from IMDb database?

I was credited in a TV series when I was 12 years old and also uploaded here in IMDb. I did not agree upon casting and acting in a small 5 second segment in a TV series to get my name uploaded to this website and also even if I did (it cannot be proved that I gave my permission, because no written contract was signed), I was underage, therefore not legally fit to take responsibility.
