It's good to have this kind of original, motivated and well-explained answers!
This is useful for the thread and this generates more answers/debates/participation.
You see, if Mojo, didn't answer, I would not post this, because I would not have what to comment. His answer gave me a reason and 'energy' to post more! I'd like to focus on the our concrete topic (because the ads themselves are a very big and very 'endless 'one).
Let's assume that we can't avoid the ads in question. Then what are our options?
Waiting for some ideas.
