They pretty much had to block entire publishing sources, so that they could get back into those stores overseas (all of their trad publishing books were being blocked in the UK by Whitesmith, for example). There are also changing laws in the UK making it illegal just to show certain covers if no opt-in has been signed up for. They'll need to change their website (and screening of books, as the publishers and authors are intentionally mis-classifying them to try to get more returns in searches) before they let them back in, I'm afraid.
Amazon has been doing something similar, but didn't do a wholesale block (some authors and publishers are being banned tho - there's no requirement for Amazon or anyone else to sell certain books, only the right of the author to publish it ... even if that means at his own expense and with limited distribution).
So, here are some freebies from Wild Rose at Amazon, for those missing the selection at Kobo:
