Attic Exhaust Can A Bathroom Exhaust Fan Be Vented Thru Attic Gable Vent?

Can a bathroom exhaust fan be vented thru attic gable vent? - attic exhaust

I know it is a gable vent to air. However, the fan is not much, just in the shower. I have a few images of horror through ventilation panels. I know that it was common practice and the pictures that I saw a bad installation. I can not generate money from the roof right now.
