I don't think it's fatherhood
Prindle has said on facebook that he's had job interviews where they google searched his name and pulled up some of the most egregious things he's written on his site. Suffice to say he did not get those jobs. So if it's actually impacting his ability to get hired I really can't blame him for wanting to delete that stuff.
Archive.org still has all his old reviews if you really want to see them.
