deviantArt has switched to a new infinite paging scheme that has broken my element hiding rules. The rules used to effectively target DIVs and IMG tags—deviantart.com##div[username="<username>"] and deviantart.com##img[data-src*="<username>"].
The new layout is instead a series of SPANs with images nested in such a way that I can't target them. The first SPAN element already contains usernames in many attributes (href, data-super-img, data-super-alt, etc.), but element hiding seems to break at this point.
