You're right, I was looking at submissions for userplane.io[1] and over-fixated on it only being submitted twice. My mistake. Nonetheless, the basic principle is the same. Looking at their submission history it appears to be almost all self-promotional and correspondingly many of the submissions are [dead]. As far as I can tell, that's what happens here. (aside: I'm just commenting based on observation of the years, I'm not anybody "official" here or anything).
