An "addblocker", as you call it... will not automaticly fix the spacing left behind and center/stretch out the logo on top of the page. You're only further proving my point.

Users shouldn't have to completely edit every square inches of the homepage from their end just to make the site's look and feel somewhat bearable.

I mean, just look at how screwed up it is! The < character was replaced with &lt; so now alot tags aren't even being interpreted for crying out loud.
