adult films

Hello,For some time now, the IMDb search engine (in France at least) has stopped displaying results for people who have appeared in adult films. This is quite problematic, as many people have had careers in both adult films and mainstream cinema, and they suddenly disappear from the searches.Is this a moral choice? Whatever one may think of adult films, they exist, they are part of the history of cinema, so it is a shame that the people who worked on them become invisible.Thank you in advance for your reply.
