“Anyway, the error must be caused by something in one of your ad orders. Here’s a list of over 3000. Look through them for bad HTML or broken images. That’s probably it.”
“You expect us to look through THREE THOUSAND active ads?!”
“Well, odds are you’ll find it in the first half.”
Okay, that’s not EXACTLY how the conversation went…but you get the idea. DoubleClick people are stupid. So is their product.
