Yes they do but you usually can't tell if they are one because other than the gamertag, they choose not to talk usually or are in clans or party chats most of the time. Majority play Call of Duty or Minecraft and Halo but I have never met one on Halo and I don't play Minecraft that much. on Call of Duty they mainly play Hardcore game types and normal Search and Destroy because they are much more realistic but its just a matter of finding them really. And if you tryin find a girl on xbox live what are the chances of her liking you, not being married, the same age, lives nearby. and is actually good looking enough that you like her , personality does matter but I would never have gone out with my girl if she was a total bithc.
