alt.com 

A dating website for people with alternative lifestyles and interest in BDSM/kinks. It is not free. To reply to messages and view profiles, you have to pay about $19.95 a month. This website is full of romance scammers and fake profiles who try to persuade you in purchasing a membership. Don't even bother with this.

Happy male kinkster on alt.com : I have had 10 women who sent me messages the first day I signed up!
His smart friend: Those are black men in Africa using women's photos and they only want your credit card information. Do you really think an attractive woman would make the first move??
