The controversy tagging system was never a way of censoring stuff for americans since none of the content is banned in the US(technically loli could be obscenity depends on art/story/ perceived age, but fakku never hosted toddercon anyways.). Actually it was for the Canadians, English Commonwealth nations and european countries with similar laws on loli and/or incest and i guess monster girl fucking..... i never knew there was, but also the vanillafags who bitch on every loli and ntr/trap/man on man hawt sex uploads since the beginning of uploading non vanilla content.
The tags missing was a bug that they just keep hidden until the unlicensed content is gone and the mags are ready for prime time. They're coming back anyways since the missing tags content are already released in the books and the two mags have quite of bit chapters with loli and ntr. Every second h-manga is incest always.
Plus you can't find these anywhere uncensored and translated. Some even you can't find in japan or in english fansubbed. Everything is on the interwebs. googleisyourpimp.son
