Yes! ALL sex dating sites are scams, usually run from America. Do not waste your money.
If you want to meet a partner stay away from any site that offers members wanting just sex. THEY ARE ALL SCAMS!
They are all scams. Unfortunately I have wasted a lot of money to find this out. Adult Friend Finder is one big scam and so is Match.com and eHarmony. You get sucked in with "free weekends" or "free to join" then get bombarded with messages from fake women asking you to contact them, but first you have to pay. As soon as you pay your membership, those women all disappear. As soon as eHaemony got my money, they told me that they could not match me with anyone! I'm not rich and don't ride a Harley but other than that I'm a normal single white male.
