I had several friend requests in facebook from profiles whose links end with "?fref=jewel". All the links had this ending term in the url. Some of the profiles were probably fake. Can anyone tell me what "?fref=jewel" means?

It simply means that the user clicked on a notification in the notification “jewel” (that’s what FB call the thingie in the top navigation bar, where notifications are shown) to get to that address …

It is just a tracking parameter.
