Hmmm I wonder if your issue might be the store preferences set to non mature/adult before the changes. For me I had that set to see all adult content years ago but those settings despite needing a credit card to change them now still allow me to see adult games in the search bar.
I can also still see the community area on those adult games. (Including Dragon Sleuth Brittany)
(It says on the top 'This Community Hub is marked as 'Adult Only'. You are seeing this hub because you have set your preferences to allow this content')
I'm sorry to say but I have no idea how to get round that problem.
