First, we're not allowed to have AdSense units designed in such a way that it mimics anything else on our site.
Finally, Google is really just expecting publishers to accept this and move on -- and I think it's ludicrious. The simple fact that they're no longer allowing any part of our sites (table colors, sizes, etc.) match any Google ad units is horrible.
Could you pull up the exact wording for this, please? I would be very interested to discuss this here in the forum.
I can understand why they would like to see such behaviour, but in practice it may be a bit difficult to follow this rule.
