**Edit: **to answer your reply above this post, you are right, relatives cannot be bought. However, keep Pakistan in mind. It's a little different in USA but imagine joint families in Pakistan (or non-joint families), most bhaabhis, nands, devraanis, and jaithaanis don't get along. So if they don't get along with me and my family, I doubt if they'll have any good words to say about us. That will screw up my rishta. As for other stuff such as graduation pics, awards, business cards etc., no problem. They are most welcome to do the check directly with the groom/bride's family
if someone has something bad to say that is a reason to do more investigation...no?
btw business cards, awards and degrees can be bought :D
