Never heard of the Sex Discrimination Act 1975
Review about Marital Affair.co.ukI signed up for this website to "investigate", and found out that if you're female you get the subscription for free! But if you're male, you must pay.
Still not heard from the company about their illegal business practice. I imagine that when females outnumber men on the site, it would reverse.
Pros
Nothing
Cons
Discriminates against people.
