I think it's ironic to draw attention to newcomers' submissions - and it might be something that malefactors would look into gaming.

On the other hand, the point of such features has always been to emulate the "I'm new in traffic - cut me some slack and keep an extra eye out for me" bumper sticker. And this outweighs the con, to me.

But it's something that's only been done on forums - bulletin boards if you will. As old as it seems, it looks like a novel approach by pg in the comments site medium.
