only use free sites dont give card details to anyone to prevent scams,most are very untrustworthy to the point of criminality
I tried AFF last year. It was a total scam. The majority of the profiles were fake. They love bomb you when you sign up on the free account. Once you pay those love bombing you don't exist. My In Box was continually filled with scammers and fake profiles. Their business design represents the worst of dating sites. They are corrupt.
