That’s a great point Dennis … the last thing you want your loyal site viewers seeing on your index page is a bunch of red x’s … or the worst case scenario – your homepage not loading at all!
On the other side of the coin, you’re putting onus back on the affiliate program to keep things in order on their end. If their program is legit and as “streamline” as they say it is, there should never be any banner issues in the first place. It’s a double-edged sword really … and I agree with both sides.
