Noon Presse, a Moroccan news site (ranked #19 in that country among all websites), published what they call a blacklist of Moroccan performers and artists who have "normalized" with Israel.
Among the seven artists named are:
One was Jamel Debbouze, an actor and director, who visited Israel in 2013 and even put on a yarmulka when visiting the Kotel.
Karima Skalli is a singer who, according to the article, was interviewed on Israeli radio for an hour but she claimed later that she didn't know who she was speaking to.
Nabil Ayouch is a producer and screenwriter whose mother is Jewish.
Chico Bouchikhi is a musician whose brother was killed by the Mossad in a case of mistaken identity. Even so, he said that he would perform in Israel if it would help peace (and apparently he has.)
Other artists made documentaries about and in Israel.
Many of these stars are quite popular, and for the most part their pro-Israel activities aren't even mentioned on their Facebook pages, so chances are that most Moroccans really aren't bothered by this.
