Arab dating sites aimed at foreigners (non-Arabs) - and their mail order bride counterparts - are, by and large, shams, and highly expensive shams, at that. Of course, there must surely be exceptions, but this is the general rule. They charge ridiculously high figures for a membership and their databases are known to be replete with fake profiles. The fake profiles are created to boost their membership numbers and encourage you to join. Most men like yourself are conned into wasting time and money.
There are literally thousands - perhaps millions - of Arab girls seeking men like yourself for a relationship. Finding them online is easy.
You need to join a major online dating community. In your profile, write down that you want to hear from Arab girls who want a serious relationship. This will make sure your profile is picked up when girls from Arab countries put in searches for men. To find thousands of Arab girls you should put in searches in your own country for the Arab ethnicity and searches in Arab nations for women seeking men. The Arab nations with, commonly, the most internet users are Egypt, Iraq, Saudi Arabia, Yemen, Syria, Sudan, and Algeria. If you do this, you will have a list of thousands of Arab women seeking men for relationships.
