You can't really trust the online sites. I have been on a couple of them and had made it very clear that I am looking for someone who is religious and considers islam to be the way of life. I met a paki online and initially I thought he is a decent guy but slowly he started asking questions which were very indecent . I gave him a piece of my mind and then blocked him from accessing my profile. Anyways I lost hope of meeting someone decent on online website and decided to delete my profile.
That can be easily solved by having your wali in the chat also, sadly, no online service has this as far as I know...
