A major British retailer has shut down its website after finding hardcore pornographic ebooks being sold through the company's online store.
WHSmith learned last week that at least 60 pornographic ebooks had slipped through its screening processes, the Guardian reported.
The London Stock Exchange-listed company immediately closed down its website and issued a response, saying it was "disgusted" by the titles concerned.
"Last week we were made aware that a number of unacceptable titles were appearing on our website through the Kobo website that has an automated feed to ours," it said in a statement.
WHSmith said the "explosion" of self publishing was having an impact on many retailers.
