It's kinda weird to hold someone accountable for things they said 10+ years ago. That's a weird "feature" of modern Life, but it's only been possible since this century.
Unless what you were trying to get away from was a fairly serious crime, there was a good chance the new people in your life wouldn't find out about it unless you told them about it.
Now the old stuff is on the internet, and you can be stuck with it unless you go to more extreme lengths like changing your name.
For this reasons and others I've given real thought to pursuing a legal name change.
