In your case yes I do understand your situation. I'm just grabbing combo videos for games for faster access, I'm not selling it inspite for additional knowledge. I'm not removing the credits attached from the videos, furtunately I'm saying nice work inside of me. For the without permission thing yes I admit apparently it's wrong, sorry to say I'm just lazy to ask permission to the author or creator. Furthermore, in our clan we do share videos eventhough that person don't ask permission to us. Our site is open in public.
