"New Poster, New Thread, Poof gone" Group"
I've noticed many new threads from new posters (normally have 1 post on their profile) add the thread and then "poof: they are gone" no more posts/threads from that poster.
This personally doesn't bother me but I've noticed all of the "unanswered threads" are from the "New Poster, New Thread, Poof gone" group.
In the meantime I will keep noticing. Have a great day :)
