I don’t have any issues with users posting lfg posts so long as personal identifying information is not publicly shared. Gamertag and screen names publicly shouldn’t be an issue I don’t think.
Of course, if you are looking for mainly PC gaming or a different console then this won’t help you much. We have a weekly, “what are you playing” pinned thread. Could be good to hop in there and see what others are playing and strike up a conversation and see if others are willing to team up.
