Have you got a response to this situation that I could pass on to the fellow? User:BBilge, I think it was. In Fixed Width, if a user modifies the layout to make it fluid, it definitely would interfer with ads displaying properly, especially ad skins, because our ad serving system wouldn't be able to tell a user had made the layout fluid. Since we're (Wikia) creating the Fluid Layout, we've also modified our ad serving system so that it will display ads properly, which is why it's not a problem for Darwin.

Basically, we have to do work on our end to make sure ads still display correctly depending on the layout - and our systems can't serve ads properly if the layout has been modified by a user.

Hope this helps answer the question. :)
