For some people, it's quite common to be "giftwraith"ed, however, for others (like me), it's extremely rare. For example, I've never been "giftwraith"ed on my Xbox, but I was once when I was in the Parish on my PC.

As the person who first replied said, Darkwraiths can invade anyone who is human, and it's only the Blades of the Darkmoon who invade people with sin.

It is also fairly common for people to have low-level characters as a form of adding extra difficulty to the game. Since the number of NGs you've played isn't taken into consideration when match-making, it is entirely possible that you'll meet a low-levelled player who has made it to NG+7, thus meaning that they have acquired a large number of items. "Giftwraith"ing is an easy way of dumping items, when you think about it this way.

Hope this helps. :)
