World Dating Partners legit?

Hey everyone I was looking around for affiliate programs and came across world dating partners and was wondering how legit they were. I read a few posts online about them being the best affiliate programs with the best commission and I've read others on how they had hard time cashing their checks. I also came across iwantu and adultfriendfinder and was wondering out of theses what was the best so I don't end up wasting my time or if there's another site that trumpets all theses. Thanks!
