A few weeks ago Google detected masking on my site (and stopped indexing by the way...). The problem is I don't know what's the source of that problem. I have some ads on my site, pop-unders from Plugrush and pop-undeer + banners from Exoclick.
Has anyone had similar problem before? What do you think is the source of detected masking?
