Why does this have a poorly drawn tag? This is the artist's (Naruho's) style.

And? Because its an artist style that means its not poorly drawn? To me, all of his works are pretty bad... de gustibus

so when it comes to this guy, it's called 'style'
but random DA uploads are not?

Bah.
Naruho has written several doujins, that are pretty good.
That establishes him as an artist, and therefore he has a style. This picture is his style.

doujin being the keyword here. that does not mean an established artist with art training.
