(REUTERS) — Singapore said on Friday it would ban popular infidelity website AshleyMadison.com from operating in the tightly controlled city-state following concerns over the spread of adultery.

The curbs on the site, which has 22 million members in about 30 countries, illustrate a struggle in Singapore over how far to relax censorship laws.

It now bans Playboy magazine, clips racy scenes from movies and blocks dozens of websites in moves that have added to its image as Asia’s “nanny state”.
