Dating website openly focuses on providing married women access to other sexual partners.  But that's illegal in France per Article 212 of the Civil Code: "Married partners owe each other the duty of respect, fidelity, help and assistance."

From the article: "...By organizing relationships between married people, it is possible to argue that [website] is inciting couples to violate their civic duty..."

Sounds like it's time to change their law, otherwise they'll have to sue every married person who cheats!  And what of people who flirt with someone's spouse, should they be sued under the same logic?  Would fashion magazines have to retool so they clearly state somewhere that all their advice is intended for wives to use with their husbands, or for single women to use on only single men?
